Abstract

All-optical triode derived from tandem wavelength conversion was realized using a distributed feed back laser diode and a semiconductor optical amplifier. The first of the converter was based on cross-gain modulation in the DFB laser diode whereby conversion from an input wavelength of 1555 nm to the wavelength of 1548 nm was accomplished in the laser diode. The 1548 nm was converted to a wavelength of a control laser in the semiconductor optical amplifier in the second stage. The output wavelength was selected using a tunable control laser and an arrayed wavelength grating filter. The output power with the input signal was controlled by the control power. The all-optical triode has the input and output characteristics in the same manner as the triode in electronics.
