Title:
OPTICAL MODULATION DEVICE, WAVELENGTH SELECTIVE SWITCH, AND OPTICAL COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066614
Kind Code:
A1
Abstract:
An optical modulation device, a WSS, and an optical communication device, relating to the technical field of optical modulation. The optical modulation device comprises a spatial optical modulator and an optical adjustment layer; the spatial optical modulator comprises a plurality of modulation units arranged in an array; the optical adjustment layer comprises a plurality of adjustment units arranged in an array; a first adjustment unit in the plurality of adjustment units is configured to switch between a first state and a second state under the action of an excitation signal; the first adjustment unit is used for guiding a received first light beam to a first modulation unit in the first state, and the first modulation unit is used for modulating the first light beam and emitting the modulated first light beam in a first direction; or the first adjustment unit is used for emitting a received second light beam in the first direction in the second state. The second light beam and the first light beam have a same wavelength, and the angles of incidence of the second light beam and the first light beam with respect to the first adjustment unit are different.
