当社のインライン型ファイバ偏光子は直線偏光を透過し、それと直交する偏光は遮断します。この製品は、各偏光子の仕様によりますが、直交偏光の光を少なくとも23 dB以上減衰するため、高い消光比の偏光状態に変換する用途にご使用いただけます( 「仕様 」タブ参照)。この偏光子は、偏光信号の消光比を高める目的でもお使いいただけます。PMピグテールが付いたタイプは、出射偏光とコネクタのナローキー(2.0 mm)をファイバのスロー軸に合わせています。実際の反射減衰量はFC/PCコネクタ付きのモデルよりもFC/APCコネクタ付きモデルのほうが高くなりますが、これは角度付きフェルールが後方反射を最小限に抑えるためです。

インライン型ファイバ偏光子は、偏光状態の分析、偏光状態のモニタと制御、PMDのモニタや偏光消光比(PER)の改善にお使いいただけます。これらは、偏波保持ファイバ増幅器、ファイバーレーザ、高速通信システム、計測などの用途に適しています。また当社では、このファイバ偏光子とともに使用できるPMパッチケーブルPMピグテール付き半導体レーザおよびPMレーザ光源もご用意しています。

逆方向での使用
このインライン型ファイバ偏光子のピグテール付きの先端には、ご使用しやすいように「Input」または「Output」の印をつけています。この偏光子は逆方向でも使用できますが、その条件では挿入損失や消光比を含む全ての仕様値が、このページや「仕様 」タブ内で示された数値と異なる場合があります。

Please provide an SM to PM version of these inline polarizers. Most of my applications involve using a fiber polarization controller and inline polarizers to go from SM to PM to control the optical power as well as polarization.

Thank you for this suggestion! I have submitted this to our internal product development team so that it may be considered for a future release.

Hi, I can see that the central wavelength tolerance for this product is +-50 nm from 1550. Do you have any measurement/data to suggest I can extend the use of this all the way, for example, to 1650 nm? How will this impact the experiment? Alternatively, do you offer something similar that operates well all the way from 1500 nm to 1700 nm? Any comments/leads/suggestions would be highly appreciated. -BR Ashik

Thank you for reaching out to Thorlabs. The polarization extinction ratio (26 db min/ 28db typ) is only guaranteed for wavelengths within the range specified, operating outside that range will impact the effectiveness of the device.

Good afternoon. I have a doubt about the in-line polarizer: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=5922 In which polarization is the output of the in-line polarizer ?? I mean, a PBS (polarization beam splitter) saparates light in its components :Horizontal and Vertical, thus in the case of in-line polarizer, which component is in the output, the vertical or the horizontal ?? (note that the reference is that the key of the connector are aligned to the slow axis) Thank you very much. Luis

Thank you for reaching out to us with this confusion. Noted on the overview page: "... the output polarization and 2.0 mm narrow key of the connector are aligned to the slow axis of the fiber."

Dear Sir/Madam, I was wondering if a 1310 nm, SM pigtailed FC/APC option would be available ? Thanks in advance

Thank you for contacting Thorlabs. For quote requests for custom items, you may reach out to your local Tech Support team (Europe@thorlabs.com in your case). Also, using a polarizer with single mode fiber will not maintain the output polarization, so we will reach out to you directly by email in this case to discuss your application further.

Hi, According to Malus's Law, polarizer has to pass 0.5 or 3dB of input light. Your specification points less than 1 dB. Where is the hint? :-) Or it is necessary to add 3 dB to spec? Thanks!
YLohia  (posted 2018-07-03 10:30:04.0)
Hello, thank you for contacting Thorlabs. The spec you are referring to is the insertion loss of the unit, which includes fiber-to-fiber coupling, etc.
bsslv  (posted 2018-05-30 03:28:26.453)
Hi, My name is Sung, and just wanna ask about this device, ILP1550PM-FC. I already know PM means Polarization Maintaining, and what is the role of the part of 'Small in-Line package' ? AND Why this device is called likes 'polarizers' ? Is this makes some polarization? As I known by checking the spec sheet, I could not found about the information whether it makes TM or TE polarization. Is it right? Yes, That's all. Thx. Best regard,
YLohia  (posted 2018-05-31 11:26:23.0)
Hi Sung, the "small in-line package" refers to the fact that the polarization module is "in-line" with the fiber and is quite small (35 mm long with a 5 mm diameter). These units can polarize light by taking in unpolarized light and only passing through one linear state (aligned to the slow axis of the fiber). TE or TM polarization only have meaning in the context of a defined reference plane. The relevant information here is that the slow axis of the fiber is aligned to the connector key, so depending on the orientation of your output fiber key, you can get a linear polarization state at any arbitrary angle.

o.puncken  (posted 2017-11-08 12:02:52.81)
Dear Sir or madam, we recently bought an in-line polarizer for 1550nm to build a linearly polarized Erbium ASE source: We pump an Er-doped non-pm fiber, to create some broad unpolarized fluorescence. We then spliced an ILP1550PM-AC to this setup and measured the PER with a combination of half waveplate and PBS, which was only 1:2. The fiber cores of the EDF and the polarizer match. An additional quarter waveplate fixes the bad PER, but in the end we need an all-fiber setup. Any ideas on this ? Best regards, Oliver Puncken Laser Zentrum Hannover e.V. Tel.: +49 511 2788 377
tfrisch  (posted 2018-01-16 04:23:36.0)
Hello, thank you for contacting Thorlabs. The most common reason for a poor extinction ratio would be a significant portion of the spectrum outside the operating band of the filter (1550nm ± 50nm). I will reach out to you to discuss the source you are using and your expected output spectrum from the fiber.
user  (posted 2017-01-31 17:36:56.1)
For the isolators with PM fiber patch-cords, which fiber axis is transmitted please? i.e. does it block the fast or the slow axis? Many thanks.
tcampbell  (posted 2017-02-02 12:34:37.0)
Response from Tim at Thorlabs: thank you for your question. The output polarization is aligned with the slow axis of the fiber, while the fast axis is blocked. The 2.0 mm narrow key of the connector is also aligned with the slow axis of the fiber, so the orientation of the connector will indicate the direction of output polarization.
emeyersc  (posted 2014-05-27 15:19:33.993)
I am interested in using the ILP1550SM to co-polarize a few different co-propagating laser fields, e.g. at 1400nm, 1550nm and 1600 nm. What happens if 1400nm light is sent through the polarizer? Does it polarize correctly but poorly, or does it transmit a different polarization than the wavelengths within spec?
myanakas  (posted 2014-06-11 10:10:46.0)
Response from Mike at Thorlabs: Thank you for your feedback. It is possible to polarize the fiber at that wavelength but we cannot guarantee the extinction ratio through the fiber. Also, the fiber may propagate a second mode so the signal may not be the best. If you mandrel wrap the fiber you can possibly eliminate that second mode.
