Abstract:
A method of manufacturing a vertical-cavity surface-emitting semiconductor laser, comprising the steps of:growing a first semiconductor multi-layered film on a first GaAs substrate;growing a second semiconductor multi-layered film, an active layer, and a third semiconductor multi-layered film on an InP substrate in that order;growing a fourth semiconductor multi-layered film on a second GaAs substrate in that order;fusing said first semiconductor multi-layered film with said second semiconductor multi-layered film under heat and pressure, followed by removing said InP substrate; andfusing said third semiconductor multi-layered film with said fourth semiconductor multi-layered film under heat and pressure, followed by removing said second GaAs substrate, whereinsaid first semiconductor multi-layered film is formed by piling up a plurality of Al.sub.x1 Ga.sub.1-x1 As layers (0.ltoreq.x1.ltoreq.1) and a plurality of Al.sub.x2 Ga.sub.1-x2 As layers (0.ltoreq.x2.ltoreq.1) one after the other by turns, in which each layer has a thickness corresponding to a value obtained by dividing an emission wavelength by a refractive index and 4;said second semiconductor multi-layered film is formed by piling up a plurality of In.sub.x3 Ga.sub.1-x3 As.sub.y3 P.sub.1-y3 layers (0.ltoreq.x3, y3.ltoreq.1) and a plurality of In.sub.x4 Ga.sub.1-x4 As.sub.y4 P.sub.1-y4 layers (0.ltoreq.x4, y4.ltoreq.1) one after the other by turns, in which each layer has a thickness corresponding to a value obtained by dividing an emission wavelength by a refractive index and 4;said active layer is formed at least from an In.sub.x5 Ga.sub.1-x5 As.sub.y5 P.sub.1-y5 layer (0.ltoreq.x5, y5.ltoreq.1);said third semiconductor multi-layered film is formed by piling up a plurality of In.sub.x6 Ga.sub.1-x6 As.sub.y6 P.sub.1-y6 layers (0.ltoreq.x6, y6.ltoreq.1) and a plurality of In.sub.x7 Ga.sub.1-x7 As.sub.y7 P.sub.1-y7 layers (0.ltoreq.x7, y7.ltoreq.1) one after the other by turns, in which each layer has a thickness corresponding to a value obtained by dividing an emission wavelength by a refractive index and 4; andsaid fourth semiconductor multi-layered film is formed by piling up a plurality of Al.sub.x8 Ga.sub.1-x8 As layers (0.ltoreq.x8.ltoreq.1) and a plurality of Al.sub.x9 Ga.sub.1-x9 As layers (0.ltoreq.x9.ltoreq.1) one after the other by turns, in which each layer has a thickness corresponding to a value obtained by dividing an emission wavelength by a refractive index and 4.
