Title:
OPTICAL SIGNAL TRANSMISSION METHOD AND DEVICE, AND WAVELENGTH SELECTIVE SWITCH
Document Type and Number:
WIPO Patent Application WO/2018/076195
Kind Code:
A1
Abstract:
Provided are an optical signal transmission method and device, and a wavelength selective switch. The method comprises: performing diffraction processing on an input optical signal to obtain signal light and cross-talk light, wherein the signal light is used for being output to a target output port in a plurality of output ports; and the diffraction processing comprises: deflecting, in a second direction, a diffraction direction of a part of or the whole of the cross-talk light, so as to output the part of or the whole of the cross-talk light to an area excepting the output ports.
