英文摘要 | PURPOSE:To reduce effective reflection factor against approximation mode, to restrain proximity mode and to improve the singleness of longitudinal mode by causing interference effect due to internal reflection. CONSTITUTION:An internal reflection plane due to replacement with a material which has smaller refractive index than that of an active layer or an adjacent waveguide to it is provided. For example, on an N type InP substrate 1, an N-In1-xGaxAsyP1-y layer 2, an N-InP layer 3, a P-InP layer 4, an N-InP layer 5 and a P-In1-x'GaxAsy'P1-y' layer 6 are grown one after another and a stripe type groove is formed. In the groove, an N-InP layer 8, an N-In1-xGaxAsyP1-y (active layer) 9, a P-InP layer 10 and a P-In1-x'Gax'Asy'P1-y' layer 11 are grown one after another and the crescent type active layer 9 is buried. In the region where the groove is not formed, crystal is not grown even by the second growth and the surface of SiO2 remains intact, where an active layer is lacked to become an internal reflection plane. |
