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