摘要： A system for transmitting information with a coherent beam being propagatable in the air is arranged to include a transmitting device having a modulator and an emitting circuit and a receiving device having a generator, a mixer, a frequency discriminating circuit, and reproducing circuit. The modulator modulates a reference light frequency (wavelength) or phase of a coherent beam to be emitted from a light source according to the signal. The emitting circuit emits the modulated beam as a divergent beam having such a power density as being safe to human eyes. The generator generates a coherent locally oscillated beam. The mixer mixes the signal beam with the locally oscillated beam and photoelectric-converts the mixed beam. The frequency discriminating circuit frequency-discriminates the a.c. component of the photoelectric-converted output. The reproducing circuit reproduces a signal from the output of frequency discriminating circuit. Any one of the transmitting device and the receiving device has a function of keeping a relative light frequency difference (wavelength difference) between the signal beam and the locally oscillated beam constant.

摘要： In a first crystal growth step, a first cladding layer, an active layer, and an optical wave-guide layer are sequentially grown on a semiconductor substrate. A diffraction grating is formed at a surface of the optical waveguide layer. In a second crystal growth step, a current block layer is grown on the optical waveguide layer having the diffraction grating. The current block layer is selectively etched to expose the diffraction grating and thus to form a stripe groove. In a third crystal growth step, a second cladding layer is grown on the diffraction grating inside the stripe groove and on the current block layer.

摘要： A semiconductor laser array includes a plurality of first wave guides extending from one end of the semiconductor laser array device, a plurality of second wave guides extending from the other end of the semiconductor laser array device, and coupling wave guides for coupling the second wave guide so that the two first wave guides are confronted. The coupling wave guides have asymmetrically divided connecting points so that the laser beam is prevented from centralizing towards the wave guides located close to the center of the semiconductor laser array.

摘要： In a diffractive element, its grating pattern is so configured that a diffraction angle of a diffracted light beam of a light source that is subject to the first-order diffraction in a diffraction area is matched with an angle of a light beam passing through the diffractive area emitted from a light source and a light source position is matched with a light originating point of the light source that emits a light beam to be transmitted, and the center of light intensity distribution is matched with that of the light source passing through the diffractive element by inclining an optical axis of the light source. A position of the diffractive element is adjusted based on an electric current value generated when a reflected return path light beam of the light source is diffracted by the diffractive element and enters the light source.
