| 英文摘要 | In a light-responsive semiconductor device in which the laser oscillation state is controlled by incident light, a layer of material having a conductivity modulatable by light is integrated in a semiconductor laser structure and is responsive to the incident light for the control of the laser oscillation state of the device. In one embodiment constituting a light logic element, a plurality of semiconductor lasers are integrated on a substrate with each respective semiconductor laser having a grating along the entirety or a portion thereof and provided with a light waveguide connecting with a waveguide of an adjacent semiconductor laser. In a bistable semiconductor laser there are provided two different conductivity type light confinement layers, an active layer comprising a multiple quantum well structure which is between the two light confinement layers, a grating provided close to the quantum well active layer. The oscillation wavelength established by the grating is shorter than the peak gain wavelength produced by the quantum well active layer. |
