シングルモード(SM)光サーキュレータは、非往復式、1方向型デバイスで3つのポートを有する部品で、数多くの用途、幅広い光学システムで使用されていま す。当社のSM光サーキュレータの中心波長は、1064 nm、1310 nm(Oバンド)、1550 nm(Cバンド)をご用意しています。また、このSM光サーキュレータには、ファイバ素線タイプ、FC/PCコネクタ付き、FC/APCコネクタ付きを選択いただけます。当社では、偏波保持(PM)光サーキュレータもご用意しています。
FBGを使ってDWDMシステムから光チャンネルをドロップするサーキュレータ
光サーキュレータは電子サーキュレータと類似しており、両者は似た機能を持っています。光サーキュレータには3つのポートがあり、光は1方向にしか進みません。ポート1から入った信号はポート2から出ていき、ポート2から入った信号はポート3から出ていきますが、いずれの場合も損失は最小限です。ポート2から入った光の損失はポート1で大きく、ポート3で入った光の損失はポート2や1で大きくなります。光サーキュレータは非往復式の光学素子です。つまりこのデバイスを通ることで起こる光の特性の変化は、逆方向に光が進む時に再現されないということです。
アイソレーションが高く、挿入損失が低いので、光学サーキュレータは、アド&ドロップマルチプレクサ、双方向励起や色分散補償デバイスとして最先端の通信システムに幅広く使われています。
サーキュレータを使用して1本のファイバ経由で2つの方向に光信号を送信できます。
左の図では、ファイバーブラッググレーティング(FBG)を用いてDWDMシステムから光チャンネルをドロップさせる用途でサーキュレータを使っている様子を図解しています。入力用のDWDMチャンネルは、デバイスのポート1に結合入力されて、FBGデバイスはポート2に接続されています。この単一波長が FBGで反射され、サーキュレータのポート2に再び、ポート3から出力します。残りの信号はFBGを通り過ぎて出力されます。
サーキュレータは、双方向から入力する光信号をそれぞれ異なる2つの光ファイバに送ることができます。サーキュレータがファイバの両端にある状態で各サーキュレータ は、1つの方向に向けては信号を1つ追加し、もう1つの方向に向けては信号を取り除く役割を果たします。右の例をご参照ください。

(posted 2024-03-21 14:04:47.613) Hello, is it OK to fire a short pulses [10-100 ns, 10-30 W peak, 10 kHz repetition frequency] into SM Fiber Optical Circulators, 1550 nm? ksosnowski
(posted 2024-03-22 02:38:34.0) Thanks for reaching out to Thorlabs. The component fibers used for these devices are found in the specs tab. Each of the component fibers has a damage threshold listed on their page for pulsed and CW damage. Additionally, we provide a short article describing the mechanisms and consequences for damaging a fiber optically, since scratches or debris can lower the threshold artificially. For pulse lasers, we can only guarantee performance following our spec for the bare fiber; while the average power seems low enough in this scenario, fast laser pulses like this must be applied at the user's discretion. We have not tested these assemblies for other potential damage mechanisms internal to the circulator so we cannot guarantee a safe pulsed damage threshold limit. Adam Wright
(posted 2023-07-20 21:40:03.297) You all should make 1550 fiber circulators that are boxed, similar to the TN1550R5A2. That would be awesome jdelia
(posted 2023-07-21 11:34:01.0) Thank you for contacting Thorlabs and for providing this valuable feedback. I can certainly forward your request over to our design engineers via our internal suggestion forum for consideration as a future product. Conner Phillips
(posted 2023-07-11 09:17:27.597) Greetings,
Could you provide feedback on whether the 6015-3-APC would be appropriate to use over the bandwidth 1450-1690 nm? cdolbashian
(posted 2023-07-13 02:24:18.0) Thank you for reaching out to us with this inquiry. While we do not advertise this circulator down to 1450, it is made with SMF28-ULTRA fiber, which works perfectly well in terms of transmission. At worst, you will get some additional insertion loss (up to 1.5dB compared to .8 of the device in-spec). Md Sikandar Ansari

(posted 2021-09-14 03:44:02.0) Hello, thank you for contacting Thorlabs. Please see our list of international distributors here: https://www.thorlabs.com/distributors.cfm. user
(posted 2021-06-16 05:43:58.42) Hello,
We would like to know whether or not the "6015-3-FC" series will support input power from a picosecond pulsed source peaking at 200W with an average power of 100mW.
Regards. YLohia
(posted 2019-07-03 03:28:58.0) Hello, thank you for contacting Thorlabs. The component fibers used for these devices are found in the specs tab. Each of the component bare fibers has a damage threshold listed on their page for pulse an CW damage. Additionally, we provide a short article describing the mechanisms and consequences for damaging a fiber optically. For pulse lasers, we can only guarantee performance following our spec for the bare fiber, as connectorizing the fiber drastically decreases the damage threshold. If you plan to use this with a picosecond pulse laser, please do so at your own discretion. abigail.sandquist
(posted 2019-01-07 12:14:12.747) Hello,
I am interested in the operational history of this product. Do you have some examples of how this product has been used in the field, and how it has performed? nbayconich
(posted 2019-01-10 11:17:23.0) Thank you for contacting Thorlabs. Most of our circulators are used in the lab rather than in the field. I do not have specific application examples to share for these circulators other than that some are used in add/drop multiplexers & optical amplifiers. phani
(posted 2018-02-20 22:33:35.86) Hello,

2. 650 nm
3. 980 nm
Thanks!

(posted 2018-02-20 13:26:07.713) What is the Mode Field Diameter at the exit of port 2 of the CIR1064-FC circulator? tfrisch
(posted 2018-02-20 01:25:37.0) Hello, thank you for contacting Thorlabs. CIR1064-FC uses HI1060 fiber which has a MFD of 6.2±0.3µm at 1060nm. This is true of all 3 ports. mjburek
(posted 2017-05-20 17:26:21.387) Is it possible to develop a fiber circulator for visible light, with either S630, S630-HP or SM600 fiber? This product would be highly valuable for our work. Thanks! nbayconich
(posted 2017-06-06 03:21:44.0) Thank you for contacting Thorlabs. We currently do not offer a stock option of our fiber circulators in the visible wavelength range but we can offer a custom version circulator. Fiber circulators at the visible wavelength range are very wavelength dependent and will have a smaller bandwidth. A Techsupport representative will contact you directly. hsun-chiahsu
(posted 2016-09-12 18:21:46.1) I'd like to ask if you can customize a fiber-based optical circulator for 980 nm cnetral wavelength (covering range from 970 nm - 990 nm). If yes, what would the price can be? tfrisch
(posted 2016-09-15 05:29:14.0) Hello, thank you for contacting Thorlabs. It looks like you are already in contact with Tech Support about this request. user
(posted 2016-06-20 09:44:00.993) Is the light arriving from port 3 directed to port 1? What is the insertion loss? (port3-->
1)
Many thanks! besembeson
(posted 2016-06-22 09:04:53.0) Response from Bweh at Thorlabs USA: Port 3 is an output port and light arriving port 3 will have high losses through port 1 or port 2. We have not measured that as it will not be a typical configuration for usage. For high throughput, port 1 exits at port 2 and port 2 exits at port 3. yinian-zhu
(posted 2013-07-10 12:02:38.553) I need a formal quotation of Fiber Optic Circulator, 1050 - 1070 nm, SMF, FC/APC for my purchase order here. Thanks. jlow

(posted 2012-07-19 12:24:00.0) Response from Sean at Thorlabs: Thank you for pointing out the inconsistency with our circulator diagrams. We are currently reviewing these diagrams and are working to recreate them properly. If you have any questions regarding the operation of our circulators, or if you wish a notification of when this update is complete, please contact us at techsupport@thorlabs.com. user
(posted 2012-07-17 18:08:46.0) Hi, you might want to change your cartoons to reflect the actual circulator you sell -- it's a little confusing since in the cartoon the light is directed 90 deg twice, while in the actual circulator, the light goes straight through and then is directed 90 deg just once. Small thing; it got me, though! Went back to the PDF and realized what was going on. Maybe can save someone else the trouble. Best, Luke user
(posted 2011-12-09 13:41:52.0) A response from Tyler at Thorlabs: You are correct, each time the light enters the circulator it experiences the insertion loss. Thank you for using our online feedback forum. bmills
(posted 2011-12-08 16:46:08.0) Can you explain the insertion loss numbers? Do you lose 1.3 to 1.9dB going from port 1 to port 2, and then lose another 1.3 to 1.9dB going from port 2 to port 3? klee
(posted 2009-11-12 10:36:49.0) A response from Ken at Thorlabs to pratheep.r29: We will check if this is possible. Meanwhile, please send your full contact information to techsupport@thorlabs.com so we can send you a quotation if this is indeed possible. pratheep.r29
(posted 2009-11-12 01:51:08.0) I need a 3-port custom made circulator with port1 to port2 having a wide spectral range i.e. 900nm~1600nm, port2 to port3 having a spectral range 900nm~1100nm. klee
(posted 2009-10-13 14:08:00.0) A response from Ken at Thorlabs to kevin.h.wilson: Which circulator do you have? Only the CIR-1310-50-APC is designed for 1310nm. The 6015-3 are for 1550nm while the OC-L-xxxx are for 1064nm or 1550nm.
The yellow/orange arrows just “help” explain the path the light takes. The coil in the middle is just a fiber. kevin.h.wilson
(posted 2009-10-13 09:20:47.0) Two things.
First have you or any of your customers ever used circulators on a standard 1gb-Ethernet network at 1310? I have tried the suggeted configuration and get intermittant behavior.
Second, in figure 2 of the circulators page I understand the red and blue arrows, but what are the yellow/orange arrows representing? Is that coil in the middle a sensor? |
