英文摘要 | PURPOSE:To form a semiconductor laser in one epitaxial growth and to improve mass producibility by providing a striped optical guide layer adjacent to an active layer and by carrying out light confinement making an equivalent refractive index of the section high. CONSTITUTION:Four layers consisting of an N-type InGaAsP optical guide layer 2, an N-type InP clad layer 3, an InGaAsP active layer 4, and a P-type InP clad layer 5 are formed on an N-type InP substrate 1 whereto a striped mesa 6 is formed. The optical guide layer 2 is formed so that a thickness of an upper part of the mesa 6 is 0.1mum and the clad layer 3 is made thin on the upper part of the mesa 6 and thick on other regions. Therefore, when a thin optical guide layer is made adjacent to the active layer 4, an equivalent refractive index increases there, thereby forming a refractive index difference optical waveguide path having a high refractive index at the mesa section 6. If a zinc diffusion layer 8 is provided and a current is collected to the mesa section 6, a semiconductor laser having a light confinement mechanism at the mesa section 6 can be formed in one epitaxial growth and mass producibility improves. |
