LCOS Method for making multi phase hologram pattern that is applied to wavelength selective switch using LCOS and wavelength selective switch using the hologram pattern

摘要

The present invention relates to a method of fabricating a multiphase hologram pattern applied to a wavelength selection switch using an LCOS and a wavelength selection switch using the multiphase hologram pattern. According to the present invention, by applying a multiphase hologram pattern to an LCOS device, And crosstalk can be greatly reduced.
