Abstract
A wavelength selective switch (WSS) apparatus is disclosed, which includes: a liquid crystal on silicon (LCOS) phase array configured for selectively diverting a certain wavelength component of light beams to continue to propagate and keeping another wavelength component of the light beams from propagating by controlling a voltage applied thereto and/or a polarization of the light beams, the LCOS phase array being provided with a first liquid crystal (LC) domain, a second liquid crystal (LC) domain, and a reflection component, the reflection component being configured to reflect a light beam input through the first LC domain back to the first LC domain and reflect a light beam input through the second LC domain back to the second LC domain; and a reflective element that is arranged to reflect the light beams output from the LCOS phase array back to the LCOS phase array.
