Title: Infrared semiconductor laser
Inventor: SUZUKI MASATOSHI
IPC: H01S5/00
Filed: 1987-06-26
Abstract: PURPOSE:To obtain an infrared semiconductor laser having a high inner quantum efficiency by making part of the optical waveguide layer an active region. CONSTITUTION:On a N<+>-InP substrate 1, an InGaAsP optical waveguide layer 2 is stacked in which the electrical conductivity is varying from semi-insulation to P-type. Further, a P<+>-InP upper clad layer 3 and a P<+>-InGaAsP contact layer 4 are constructed thereon. Positive holes which have continuously been injected from the P-type InP layer 3 proceed to the boundary of the substrate 1, but they combine with electrons at the hetero junction plane and emit a light. The light emission wavelength is two times the wavelength of the forbidden band since the InGaAsP at the hetero interface is an intrinsic semiconductor. In this structure, the carrier injection efficiency is high, and by changing the composition of the intrinsic semiconductor InGaAsP, the oscillation wavelength can be changed from 2mum to about 3.35mum.
