Polarization-insensitive optical switch and multiplexing apparatus.

摘要

The invention relates to a polarization-insensitive optical switch apparatus for switching a collimated input beam between two output paths. The invention provides a new and and improved polarization-insensitive optical switch apparatus which is very fast as compared to mechanical switching by using two electro-optical crystals (102, 103), each of said crystals having a surface facing the other crystals, said surfaces being connected to each other by a dielectric beam splitting coating (104).
