Variable Polarization Beamsplitter Kit Components*
1 Multi-Axis FiberBench (FT-51X60)
3 FiberPorts (PAF-X-2-C)
3 Wall Plates (HCA3)
1 Polarization Beamsplitter (PSCLB-VL-1550)
1 Half-Wave Plate Module (RABH-1600)

*The kit is supplied assembled but not aligned. Fiber cables can be purchased separately.

The Variable Polarization Beamsplitter Kit is based on Thorlabs' Multi-Axis FiberBench. A PM fiber can be attached to the input FiberPort, which collimates the output. The polarization of this beam is then rotated with a half-wave plate. By changing the orientation of the wave plate, the ratio of the vertical to horizontal State of Polarization (SOP) is changed, which then affects how much signal is transmitted and reflected through the polarizing beamsplitter cube. The beamsplitter is designed to transmit the P component and reflect the S component.

The average P-component transmittance is >96% (<1.5% surface reflection) and the average S-component reflectance is >98%, which leads to an excellent extinction ratio. Please see the Graphs Tab for more information. The extinction ratio of the transmitted P-component and transmitted S-component is >1000:1. The split ratio is continuously variable from 0 to 30 dB and is dependent on the polarization extinction ratio from the input PM fiber and the spectral line width when Δλ ≤ 3 nm.

A response from Adam at Thorlabs: I can provide you with more information and will make sure that the website is updated to include this information. The PBS cubes are designed to transmit the P component and reflect the S component. The P component has a tranmission > 96% and a reflection 98%. The extinction ratio of the transmitted P-component and reflected S-component is > 1000:1.

Hi there, Can you send us some product of PBS, polarization beam splitter, or can you introduce a little more about the current product as well? Thanks, Zhizhong
