Title: Semiconductor laser
Inventor: OSHIMA MASAAKI
IPC: H01S5/185
Filed: 1986-12-26
Abstract: PURPOSE:To oscillate fine spotty laser beams by introducing beams in the direction horizontal to a substrate into the substrate, forming a reflective surface at 45 deg. while diaphragming beams by a lens shaped to the substrate. CONSTITUTION:An N-InP clad layer 2, an N-InGaAsP active layer 3, a P-InP clad layer 4 and a P-InGaAsP layer 5 are grown onto an N-InP substrate 1 in succession. An ohmic electrode 6 is evaporated and patterned, and these layers are worked at an angle of 45 deg. until they reach to at least the N-InP clad layer through etching. The N-InP substrate 1 is polished, and a resist is mounted circularly. When the substrate is heated, the resist takes a shape that the central section of the resist is thickened and a peripheral section is thinned through thermal deformation. When such a wafer is reactive ion-etched using CCl4 gas, an InP lens 9 can be formed by the retreat effect of the resist. In the laser, the two InP lenses and the active layer are operated as an optical resonator while fine spotty laser beams are acquired by a lens effect though beams elliptically spread in conventional lasers.
