Phoenix Photonics polarization switch enables the conversion
of an input linear polarization state aligned on the input polarization
maintaining fiber axis to be switched between either of the orthogonal
output axes. For example an input on the slow axis can be converted to
the fast axis at the output or modulated between the fast and the slow
axis. This device has been designed to be flexible and easy to operate
requiring only a controlled current source for applications in which control
of polarization between orthogonal states is required.
An in-line fiber polarizer
integrated at the input to provide a highly linear polarization state
is optional. |
|
Option 1 - Standard: This
version allows switching between either axis of the output fiber for
a single axis input. This option includes
an integrated fiber polarizer in front of the waveplate aligned to the
slow axis of the input fiber. The role of the polarizer is to ‘clean’
the linear input state. |

will operate over full wavelength range, higher current is required at
longer wavelengths to achieve switching. |
