Bonacom' Polarization-Maintaining Fiber-Based Polarization Beam Splitters are designed to split a single input into its orthogonal linear polarizations through two fiber outputs. The devices feature two legs of polarization-maintaining fiber on one side of a calcite prism and one leg of polarization-maintaining fiber on the other. These polarization beam splitters are frequently used in erbium-doped fiber amplifier or Raman amplifier.

For device with connector, IL is 0.3dB higher, RL is 5dB lower, ER is 2dB lower.
The default connector key is aligned to slow axis.

Routing path is from port 3 to 1,2, Here are three options of polarized state from Port 3 to Port 1 & 2:

Option 1, SM to PM,

Port 3, Circularly polarized light in,

Port 1: 50%,Linear polarized light out, through slow axis, Port 2: 50%,Linear polarized light out, through slow axis

Option 2: PM to PM, port 3 is slow axis 0° aligned to port 1

1.Port 3, Linearly polarized light in, through slow axis,

Port 1: 100%,Linear polarized light out, through slow axis, Port 2: 0%

2.Port 3,Linearly polarized light in, through fast axis,

Port 1: 0%, Port 2: 100%,Linear polarized light out, through slow axis

Option 3:PM to PM,port 3 is slow axis 45° aligned to port 1

1.Port 3, Linearly polarized light in, through slow axis,

Port 1: 50%,Linear polarized light out, through slow axis, Port 2: 50%,Linear polarized light out, through slow axis

2.Port 3, Linearly polarized light in, through fast axis,

Port 1: 50%,Linear polarized light out, through slow axis, Port 2: 50%,Linear polarized light out, through slow axis
