Abstract
A resonant-structured optical transistor includes a nonlinear medium which generates a second harmonic wave through second-order nonlinear interaction with an incident pump wave, and generates an amplified signal wave and a converted wave having a difference frequency through second-order nonlinear interaction between the incident signal wave and the second harmonic wave, a first mirror which transmits, to the nonlinear medium, the pump wave or the signal wave, and reflects the second harmonic wave on one surface of the nonlinear medium, and a second mirror which transmits the pump wave, the signal wave, or the converted wave, and reflects the second harmonic wave on another surface of the nonlinear medium. The pump wave is incident to the nonlinear medium through the first mirror in a first operation mode, and the pump wave and the signal wave are incident to the nonlinear medium through the first mirror in a second operation mode.
