英文摘要 | PURPOSE:To provide a semiconductor laser element capable of alleviating requirement for width of an active layer required for fundamental horizontal mode oscillation by providing a semiconductor layer having composition of In1-x', Gax', Asy', P1-y' different from that of the active layer and doped with Fe. CONSTITUTION:On an N-type InP substrate 1, there are deposited an N-type InP clad layer 2, an In1-x, Gax, Asy, P1-y active layer 3, a P-type InP clad layer 4 and an InGaAsP cap layer 5 sequentially in that order. Then, the structure is etched to form a mesa extending from the layer 5 to the substrate The opposite sides of the mesa are filled with an In1-x', Gax', Asy', P1-y' layer 9 by a vapor growth method. An SiO2 film 6 is deposited thereon and P- and N-type electrodes 7 and 8 are provided. The high resistance In1-x', Gax', Asy', P1-y' layer 9 has a band gap wavelength of 1mum and is doped with Fe to have resistivity of 1X10OMEGA.cm. When oscillation wavelength is 3mum and the active layer 3 has thickness of 0.15mum, cut-off width of fundamental horizontal mode is about 2mum, wider than 3mum as obtained by the prior art. |
