Title:
WAVELENGTH SELECTIVE DEVICE AND CORRESPONDING SWITCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/001533
Kind Code:
A1
Abstract:
A wavelength selective device, which comprises: an input/output array (10), an switching control assembly (20), a dispersion device (30), and an optical polyhedron (40); the optical polyhedron (40) comprises a first curved surface (401) and at least one light-transmitting surface; the input/output array (10), the switching control assembly (20), and the dispersion device (30) are mounted on at least one light-transmitting surface; the input/output array (10) is used for inputting a multi-wavelength optical signal into the optical polyhedron (40), and for receiving at least one single-wavelength optical signal from the optical polyhedron (40); the switching control assembly (20) is used for modulating optical signals incident into the switching control assembly (20); the dispersion device (30) is used for dispersing optical signals incident upon the dispersion device (30); and the first curved surface (401) is used for shaping and changing the direction of optical signals incident upon the first curved surface (401). The wavelength selective device has few components, is simple to assemble, involves optical signal reflection occurring inside an optical polyhedron (10), and has good performance stability.
