Abstract
An optical switch that switches an optical path of signal light obtained by modulating carrier light by a control signal and a data signal, includes an optical modulation element that reflects or refracts the signal light and includes cells each having an independently set phase modulation amount with which the signal light is emitted in a direction corresponding to a ratio of a period of the control signal to a period of the carrier light.
Claims7
An optical switch that switches an optical path of signal light obtained by modulating carrier light by a control signal and a data signal, comprising:
- an optical modulation element that:
- reflects or refracts the signal light, and
- includes cells each having an independently set phase modulation amount with which the signal light is emitted in a direction corresponding to a ratio of a period of the control signal to a period of the carrier light.
A switching method comprising:
- switching an optical path of signal light obtained by modulating carrier light by a control signal and a data signal;
- reflecting or refracting the signal light with an optical modulation element including cells each having an independently set phase modulation amount with which the signal light is emitted in a direction corresponding to a ratio of a period of the control signal to a period of the carrier light.
