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 an assembly structure of an optical integrated circuit device for assembling a semiconductor laser device and an optical integrated circuit substrate, the semiconductor laser device includes a recessed/raised structure. On the other hand, the optical integrated circuit substrate includes another recessed/raised structure to fit the recessed/raised structure of the semiconductor laser device. These recessed/raised structures are formed so that their cross sections taken parallel to the layers forming the semiconductor laser device are symmetric in shape about the respective optical axes of the semiconductor laser device and the optical integrated circuit substrate. Further, the recessed/raised structures preferably contain a tapered portion as part of its contour, the taper forming a prescribed angle with the respective optical axes. Thus, the mounting accuracy required to achieve the prescribed coupling efficiency in the optical integrated circuit device can be obtained by simple mechanical operations.
