Title: Optical waveguide, semiconductor optical integrated element, and manufacturing method thereof
Inventor: YAMATOYA TAKESHI
IPC: H01S5/026
Filed: 2007-05-24
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the reflection of light at the boundary between a ridge-type waveguide and a high-mesa-type waveguide that are formed on the same substrate of a semiconductor optical integrated element.  <P>SOLUTION: A semiconductor laser section I, an optical modulator section II, and an isolation section III that separates the semiconductor laser section I from the optical modular section II are provided on a p-type InP substrate 2. In the structure, the height of a surface extending to both outsides of a mesa stripe 12 of the semiconductor laser section I is higher than the height of the surface extending to both outsides of the mesa stripe 12 of the optical modulator section II. The height of the surface extending to both outsides of the mesa stripe 12 of the isolation section III becomes gradually lower from the semiconductor laser section I side toward the optical modulator section II side. This structure reduces the reflection of light at the boundary between the semiconductor laser section I and the optical modulator section II, thereby suppressing the deterioration of single-wavelength properties of a laser.  <P>COPYRIGHT: (C)2008,JPO&INPIT
