支持FC/PC和FC/APC接头
确定的偏振控制允许转换任意偏振态
机械和热稳定性，通过360°旋转实现精确的偏振控制
如需用于特殊波长或者定制对准套件，请联系技术支持techsupport-cn@thorlabs.com

Thorlabs的FiberBench偏振控制器套件可以将任意偏振态的输入转化为任意偏振态的输出。这些控制器使用单轴FiberBench，侧边有两个FiberPort安装在HCA3壁装插座板上。利用安装在两个FiberPort之间的四分之一波片、半波片和另一个四分之一波片(按照这个顺序)，可将输入偏振态转变为确定已知的输出偏振态。每个波片都可以进行360°精确连续地旋转。

优于传统的光纤桨式控制器
FiberBench偏振控制器套件具有与传统的光纤桨式控制器相同的功能，但是它的偏振操控更确定更稳定。由于它没有滞后，因此，在只有输入偏振态(SOP)的情况下也有可能在任何时刻预测控制器的输出SOP。桨式控制器的SOP在没有偏振态测量仪时并不能直接确定。与传统的光纤桨式控制器不同，FiberBench偏振控制器能与保偏光纤或者单模光纤配合使用，且不需要熔接。此外，得益于FiberBench系列先进的设计，它还具有高热稳定性和机械稳定性。波片可为用户提供360°连续旋转和精确控制，相比桨式控制器，此平台更具可控性和稳定性。

请问如果某一偏振态的激光通过这个PC后偏振态变为另一偏振态，这个变化后的偏振态反向通过这个PC会被这个PC变为初始的偏振态吗？

Hello, we try to collimate a beam coming from a fiber P3-780PM-FC-1 using one of the fiber port on FBP-B-FC. However, it doesn't seem to collimate the beam. Here is what we did and result: 1.We prealigned the tilt plate so that it is orthogonal to the optical axis as suggested by the alignment procedure. 2. We adjusted the x-y adjusters such that the beam can go though a 1mm pin hole located at the center of the other fiber port on the bench. 3. We put a beam profiler at about 10cm away from the fiber port to measure the beam size. We found that when moving the beam profiler closer to the lens (to 8cm), the beam size is decreasing (to <0.43mm). 4. We turn the z adjusters clockwise by the same amount (1/4 turn) each time and found the beam size at 10cm always increasing. This seems to show that at the prealigned z position, the lens is still more than a focal length away from the fiber end. We doubt the lens is incorrectly mounted. Do you have any suggestions? We also tried to do fiber coupling on the other end starting from the prealigned position. However, we could only get <40% coupling by just turning the x-y adjusters while turning z adjusters will only decrease the coupling. (Our guess is that the prealigned position is not very stable as the z adjusters are just in contact with the tilt plate) Thank you!

Hello, thank you for contacting Thorlabs. From your description, it is possible that the connector key on the fiber is not fully seating into the key receptacle on the FiberPort. I have reached out to you directly to troubleshoot further.

Hi, The insertion loss of the FBP-C-FC is 0.6dB. Is there a typical minimum loss of the PC-FFB-1550 at the best condition for reference? I adjusted it to the best condition was ~2dB loss. I would like to know if it could be better or it is just normal. Thank you. Jeff

Can I replace the HWP with a rotatable linear polarizer? I would like to use this setup for measurement of Stokes parameters of (pulsed) light in a fiber.

Hello, thank you for contacting Thorlabs. Yes, you can replace the HWP with a linear polarizer. I have reached out to you directly regarding this.

How to remove the quarter-wavelength plates on the Fiberbench Polarization Controller Kit? The accessory screw-drivers are not matched with the screws under the waveplates.

YLohia (posted 2018-11-30 08:37:24.0)

The waveplate module does not need any screw drivers to be removed from the FiberBench -- you can simply pull it off by hand. I have reached out to you via email to get more details on what you're attempting to do.

Could you explain the working principle of your FiberBench Polarization Controller Kit for incident light with linear polarization? I see two borderline cases: 1. input pol axis not aligned to material axis of 1st l/4 plate -> elliptically polarized light -> counter clockwise elliptically polarized light after l/2 plate -> linearly polarized light after 2nd l/4 plate 2. input pol axis aligned to material axis of 1st l/4 plate -> linearly polarized light -> pol axis is rotated about 2 alpha after l/2 plate -> elliptically or linearly polarized light after 2nd l/4 plate depending on rotation So could you describe a practical procedure how to control the polarization state with this setup deterministically? And what is the advantage compared to using a single l/2 plate? Thanks, Thomas

nbayconich (posted 2018-04-11 09:34:07.0)

Thank you for contacting Thorlabs. A 1/4 retarder will transform any elliptical state into a linear state. The 1/2 wave will then rotate the axis of any incident state. If you have fiber in and free space out then you could get by with 1/4, 1/2 to produce any state at any orientation. If you output to SM fiber then you need 1/4, 1/2, 1/4 and the last 1/4 will undo any ellipticity that the output fiber introduces into the beam A practical way to control your polarization state for example would be say using a PM fiber with linearly polarized light input onto the first quarter waveplate. If you align the input linear polarized light to 45º of the fast or slow axis of the first quarter waveplate your output will become circularly polarized. After the first quarter waveplate you can then use the half waveplate to change from left hand circularly polarized light to right hand and vice versa. The position of the fast and slow axis of the half waveplate will not matter. Of course if your linear polarization is not aligned at 45º to your quarter waveplates axis you will get an elliptical state. Assuming you maintain circular polarization (right hand) upon the half waveplate then change your circular polarization to left hand circular, once your left hand circular beam is incident on the second quarter waveplate you can change back to linear polarization but with the plane of polarization rotated by 90 degrees, in other words changing your initial vertical linear polarization to horizontal polarization or vice versa. The advantage to this setup compared to just using a single half waveplate is that if only using a half waveplate with a linearly polarized source you can only rotate the orientation of the linear polarization but not change from linear to circular or an elliptical state. In order to get and elliptical state or change from linear to circularly polarized light you will need a combination of quarter and half waveplates.

Hello: I am interested in your "FiberBench Polarization Controller Kit" products(PC-FFB-1550). Could you please give us the product's spec. (We want to know the PER of this element). Thank you~ Hua-Kung Chiu

tfrisch (posted 2017-10-06 04:00:13.0)

Hello, thank you for contacting Thorlabs. The waveplates will change the polarization state, but not the degree of polarization. I will reach out to you directly to discuss how you might define PER for a system like this, but the degree of polarization should be very similar on the input and output.

Dear Concern person, Could you explain more detail about "FiberBench Polarization Controller Kit". I can use it for connector PR measurement ,Right? Do you have another connector adapter for change? (LC , SC , MU etc...) Best regards, Pinyo Somean

Response from Javier at Thorlabs to ygyang2004: Thank you very much for contacting us. The components in the PC-FFB-1550 polarization controller can certainly be disassembled. Also, we can offer a version with different components as required in your application (we actually use the PAF-X-2-C in this controller). Keep in mind that at different wavelengths the resulting insertion loss will most likely be different. I will contact you directly for further support.
