摘要：The present invention discloses an optical signal control method and apparatus,
and an optical switch matrix control method and apparatus. A first optical couplerperforms optical coupling processing on an optical signal input from an input port, tosplit the optical signal into two paths of optical signals; a phase shifter performs phaseprocessing on the two paths of optical signals, so that a phase difference exists betweenthe two paths of optical signals on which phase processing has been performed; and asecond optical coupler performs optical coupling processing on the two paths of opticalsignals between which the phase difference exists, to output an optical signal from a firstoutput port and/or a second output port. In this way, a problem of a low reaction speedof an existing optical switch cell that exists when the optical switch cell implementsoptical signal broadcast can be resolved.
