| 英文摘要 | A semiconductor optical element includes a semiconductor substrate or a semiconductor layer formed on a semiconductor substrate; a plurality of stripe-shaped grooves each having a rectangular cross-section whose width is sufficiently narrow to occur a quantum effect, formed on the semiconductor substrate or the semiconductor layer in parallel with each other at an interval sufficiently narrow to occur a quantum effect or a plurality of rectangular-shaped grooves having a width and a length sufficiently narrow to occur a quantum effect, formed on the semiconductor substrate or the semiconductor layer in a checkered arrangement; and a structure in which a quantum well layer whose thickness is less than the depth of the groove and sufficiently thin to occur a quantum effect and a barrier layer whose thickness is larger than the depth of the groove are alternatively laminated, which structure is provided on the bottom surfaces of the grooves and regions between the adjacent grooves. As a result, an active region comprising a plurality of quantum wires or quantum boxes can be obtained by a simple production process. In addition, this quantum wire or quantum box structure can be employed for an active region of a ridge type semiconductor laser, an inner stripe type semiconductor laser or the like. |
