Abstract

PURPOSE:To obtain high frequency light signal from a light transmitter by forming first and second light waveguides through an isolation groove on a single semiconductor substrate and arranging a light oscillator on one waveguide, a light gate disposed at both sides of the oscillator, and one light gate on the other waveguide to couple them in operation. CONSTITUTION:A light waveguide and a buffer layer having lower refractive index than the waveguide are laminated on a semiconductor substrate 1 made of hybrid crystal of elements in Groups III to V in periodic Table, a deep groove is formed in the substrate 1, and two light waveguides made of the light waveguides 2, 6 and buffer layers 3, 3' are produced. Then, there are arranged a light oscillator 4 for amplifying the light signal propagating in the waveguide 2 on one buffer layer 3, and light gates 5, 5' made of electrophoto absorption effect cells for executing gate operation for the light signal at both sides of the oscillator 4. One light gate 7 is provided on the other buffer layer 3', to select the light pulse via the oscillator 4, the gates 5, 5' so as to abruptly modify the light via the gate 7 into sharp modified light.
