摘要： A semiconductor light emitting element is disclosed, which is provided with a light emitting region having a diffraction grating formed by periodic corrugations, a modulation region having an external waveguide layer optically connected directly to the light emitting region and a pn junction separated from a pn junction of the light emitting region and a window region formed of a semiconductor having a larger energy gap than that of a light emitting layer of the light emitting region and extending from at least one end of the light emitting region and the external waveguide layer. The refractive index of the external waveguide is varied through utilization of the electrooptic effect so that the frequency or phase of light stably oscillating at a single wavelength is precisely controlled or modulated. In particular, when the window region is formed only outside the light emitting region, frequency modulation is carried out, and when the window region is formed at least outside the modulation region, phase modulation takes place.

摘要： A semiconductor laser, which comprises a substrate of InP, an active layer, and two clad layers holding therebetween the active layer, and which is constructed so that the refractive index of the active layer may be larger than the refractive indexes of the two clad layers. In one of the two clad layers, the refractive index of a region adjacent to a radiation region in the active layer is larger than the refractive index of a region adjacent to a non-radiation region in the active layer. The refractive index of the other clad layer is equal to the refractive index of that region of said on clad layer adjoining the radiation region or the non-radiation region. The thickness and width of the radiation region of the active layer are selected so that the semiconductor laser may oscillate in the fundamental transverse mode. A buffer layer may be further provided between the active layer and one of the two clad layers.

摘要： An optical modulation device is disclosed in which a difference between the photon energy of incident light and the band-gap energy of the modulation waveguide layer is set to a value greater than 50 meV to thereby suppress the degradation of the modulation voltage and the modulation band width which is caused by an increase in the intensity of incident light and in that the optical modulation device is formed in a predetermined length to thereby decrease the modulation voltage. The energy gap of the optical waveguide layer of the optical modulation device is varied continuously or discontinuously in the direction of its thickness to provide a constant absorption coefficient thickwise of the optical waveguide layer so that the electric field intensity distribution in the optical waveguide layer is compensated for, by which overlap of the light distribution and the absorption coefficient is increased so as to decrease the modulation voltage and broaden the modulation band by the reduction of the length of the device. The composition, thickness and stripe width of the optical waveguide layer are changed so that its absorption coefficient increases from the light receiving end face of the optical waveguide layer toward its light emitting end face, thereby making the number of carriers absorbed per unit length substantially constant in the direction of travel of light.
