| 英文摘要 | PURPOSE:To make it possible to perform the favorable waveguide of light without showing hysteresis characteristics by a method wherein regions, which have a band gap energy laser than that of a plurality of active layers and are transparent with respect to wavelengths of emitted light, are formed at regions pinched between the active layers. CONSTITUTION:Regions 16, which have a band gap energy larger than that of a plurality of active layers 2 and are transparent with respect to wavelengths emitted light, are formed at regions pinched between the active layers 2. Accordingly, the regions 16 do never act as a saturable adsorption region, whose photo absorption coefficient is changed by the intensity of light. Owing to this, an optical loss in the regions 16 is also small and hysteresis characteristics are never shown. Thereby, the favorable waveguide of light can be performed by an optical waveguide layer 4 being linked together continuously. |
