英文摘要 | PURPOSE:To improve heat dissipation from an element surface, and enhance element characteristics and reliability, by forming constant undulations on the side wall part or the slant part of a second stripe mesa, and providing an electrode formed on the undulations with unevenness. CONSTITUTION:On an N-type InP substrate 11, the following are formed in order; an N-type InP clad layer 12, an N-type GaAsP active layer 13, and an N-type InGaAsP optical guide layer 14. After a diffraction grating having a specified pitch is formed on a wafer wherein the above layers are subjected to crystal growth, a first stripe mesa is formed by performing mesa etching in a stripe type. A P-type InP clad layer 15 is formed on the substrate 11 and the first stripe mesa. A second stripe mesa is formed so as to reflect the form of the first stripe mesa. A slant surface having inclination to the surface of an active layer and undulations is formed on the second stripe mesa. Said undulations are reflected on a P-type InGaAs contact layer 16. Further, an N-type ohmic electrode 18 is formed on the contact layer 16. |
