| 英文摘要 | 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. |
