摘要
An optical limiter includes a nonlinear medium that changes its own refractive index in accordance with an intensity of incident light, and outputs the incident light in a different direction depending on the refractive index, a first incident section by which reference light with a predetermined intensity and an optical signal with a modulated intensity is made incident on the nonlinear medium, a second incident section by which auxiliary light is made incident on a portion in the nonlinear medium through which the reference light and the optical signal pass, and an inverse output section that is provided at an incident position of the reference light outputted from the nonlinear medium when the optical signal is off, and outputs an optical signal obtained by inversion of the intensity of the incident light.
