20100022043SEMICONDUCTOR LASER DEVICE AND METHOD OF MANUFACTURING THE SAME - A method of manufacturing semiconductor laser device capable of reducing κL, with manufacturing restrictions satisfied, is provided. In a distributed-feedback or distributed-reflective semiconductor laser device, immediately before burying regrowth of a diffraction grating, halogen-based gas is introduced to a reactor, and etching is performed on the diffraction grating so that each side wall has at least two or more crystal faces and a ratio of length of an upper side in a waveguide direction to a bottom side parallel to a (100) surface is 0 to 0.3. And, a reactive product formed on side surfaces of the diffraction grating and in trench portions between stripes of the diffraction grating at an increase of temperature for regrowth is removed. Therefore, the diffraction grating with reduced height and a sine wave shape is obtained, thereby κL of the device is reduced. Thus, an oscillation threshold and optical output efficiency can be improved.01-28-2010
20110233708SEMICONDUCTOR LIGHT RECEIVING DEVICE AND METHOD OF MANUFACTURING THE SAME - Provided is a semiconductor light receiving device including: a semiconductor substrate; a semiconductor layer laminated on the semiconductor substrate and including an upper surface portion; a reflecting film formed to cover the upper surface portion of the semiconductor layer and including a principal reflecting region and an upper surface; and an upper electrode formed to cover at least one portion of the upper surface of the reflecting film, and including a junction portion extending through the reflecting file to be provided in contact with the upper surface portion of the semiconductor layer, the junction portion of the upper electrode surrounding a portion of a circumference of the principal reflecting region of the reflecting film, the principal reflecting region being connected to a region of the reflecting film located outside the junction portion, in which the semiconductor light receiving device detects light entering from another side of the semiconductor substrate.09-29-2011
20120008895SEMICONDUCTOR OPTICAL DEVICE, OPTICAL TRANSMITTER MODULE, OPTICAL TRANSCEIVER MODULE, AND OPTICAL TRANSMISSION EQUIPMENT - Provided is a semiconductor optical device, which has a buried heterostructure structure and is formed in a structure capable of reducing a parasitic capacitance to further improve characteristics thereof, and also provided are an optical transmitter module, an optical transceiver module, and an optical transmission equipment. The semiconductor optical device includes a modulator portion for modulating light input along an emitting direction and radiating the modulated light, the modulator portion including: a mesa-stripe structure, which includes an active layer and extends in the emitting direction; and a buried layer provided adjacent to each side of the mesa-stripe structure, in which a distance between a lower surface of the buried layer and a lower surface of the active layer is 20% or more of a distance between the lower surface and an upper surface of the buried layer.01-12-2012
