Title: Semiconductor light emitting device
Inventor: WAKAO KIYOHIDE
IPC: H01S5/11
Filed: 1985-12-27
Abstract: PURPOSE:To improve a light taking out efficiency and increase a device reliability, making the reflection index of a first cleavage surface of light taking out side smaller than that of the region of a second cleavage surface side. CONSTITUTION:Corrugation 10 is partly formed on the boundary surface between a substrate 1 and a light waveguide layer 2. In the case where the optical axis length of a laser is 300nm, the period and the depth of the corrugation are 2,000Angstrom  and 500Angstrom respectively, in the range of about 100mum in contact with a cleavage surface 9. By a liquid phase epitaxial growth method, a 0.15mum thick light waveguide layer 2, a 0.1mum thick undoped InGaAsP layer 3, a 2mum thick p-InP clad layer 4 and a 0.2mum thick p<+>-InGaAsP contact layer 5 are laminated in order. The reflection index of a cleavage surface 8 is 0.31 in this laser structure, but that of the cleavage surface 9 containing the corrugation can be 0.5, which improves light extracting efficiency. A dielectric film 11 of low reflection index can be laminated on the cleavage surface 8 from which the light is extracted.
