Title: Semiconductor optical switch and its manufacture
Inventor: KURIMA KAZUNORI
IPC: G02F1/313
Filed: 1988-07-25
Abstract: PURPOSE:To improve low-loss characteristics and to obtain a semiconductor optical switch which has no wavelength dependency by implanting carriers in a part of a waveguide layer through an area with relatively low resistance in a clad layer other than a high-resistance area with a voltage applied between 1st and 2nd electrodes. CONSTITUTION:The semiconductor optical switch is constituted in double heterostructure by sandwiching the waveguide layer 6 between a semiconductor substrate 2 of a 1st conduction type having a forbidden band larger than its forbidden band and the clad layer 8 of a 2nd conduction type from above and below. Consequently, the low-resistance area is formed at a part of the waveguide layer 6 by plasma effect. Then incident light is reflected totally at a boundary without depending upon its wavelength. Further, the entire surface of the waveguide 6 is a low-carrier layer sandwiched between the semiconductor substrate 2 which has high carrier density and clad layer 8 and then the loss is reduced. Consequently, optical switching is carried out at a high extinction ratio with reduced transmission loss.
