英文摘要 | PURPOSE:To eliminate the reflection of the coupling section by a method wherein the active waveguide of the title device is embedded in the external waveguide and the propagation constants and the electric field distribution in both regions of these waveguides are matched. CONSTITUTION:A GaInAsP active waveguide layer 2 and a GaInAsP protection layer 3 are successively grown on an n-InP substrate 1, thus preparing a wafer 5 Next, with an active waveguide region 52 remaining, the other external waveguide regions 53, 54 are selectively etched to the top of the substrate; further, primary gratings 55, 56 are formed on the substrate. Then, a GaInAsP external waveguide layer 4, a p-InP layer 5, and a p-GaInAsP cap layer 6 are successively grown over the whole surface. Thereafter, a current stricture structure layer consisting of a p-InP layer 7, an n-InP layer 8, and a p-GaInAsP layer 9 is formed by reverse mesa selective etching in a lateral direction through embedding. This process can eliminate most of the generation of reflection or scattering by good coupling between the active waveguides and external waveguides. |
