Title:
LIQUID CRYSTAL ON SILICON (LCOS) APPARATUS AND WAVELENGTH SELECTIVE SWITCH (WSS)
Document Type and Number:
WIPO Patent Application WO/2023/093063
Kind Code:
A1
Abstract:
A liquid crystal on silicon (LCOS) apparatus (201) and a wavelength selective switch (WSS) (101). The LCOS apparatus (201) comprises a metasurface (303) and a liquid crystal cell (302); the metasurface (303) can convert the polarization direction of a received optical signal having the polarization direction being a first direction into a second direction, and convert the polarization direction of a received optical signal having the polarization direction being the second direction into the first direction; and the liquid crystal cell (302) can adjust, according to a target voltage, the phase of an optical signal having the polarization direction being the first direction in the optical signals outputted by a first transparent electrode (301) and the metasurface (303). Hence, the LCOS apparatus (201) can perform polarization diversity processing and conversion processing on the optical signals by means of the metasurface (303). The implementation mode of the metasurface (303) is simple, the occupied size is small, the complexity of a device is reduced, the construction cost of the device is reduced, and the implementation of technical popularization is more facilitated. The WSS (101) comprises the LCOS apparatus (201).
