OPTICAL SWITCHING WITH FERROELECTRIC LIQUID CRYSTAL SLM

摘要

PROBLEM TO BE SOLVED: To provide an optical switch which reduces crosstalk and insertion loss and is independent of polarization of light.

SOLUTION: An optical switch uses two ferroelectric liquid crystal spatial light modulators with an interconnect region in between. The switch uses bulk lenses to focus light from an input fiber array to a first spatial light modulator, and from the second spatial light modulator to an output array. Each spatial light modulator displays a respective hologram selected from a previously calculated set, to cause a desired switching of light from the input fiber array to the output array.
