摘要： An optical assembly structure is disclosed, wherein a semiconductor element (2) generating a large amount of heat and a high impedance optical element (3) can be mounted with low optical loss on the same semiconductor substrate (10) having an optical waveguide (1) formed thereon.The element (2) generating a large amount of heat is mounted on a terrace (11) of the semiconductor substrate (10) directly or through an insulating layer having a thickness of submicron order, while the high impedance element (3) is mounted in a groove which is etched into the semiconductor substrate (10) to such an extent that the optical axis of the high impedance element (3) mates with the optical axis of the optical waveguide layer (1) formed on a recess in the semiconductor substrate (10). The optical axes can be adjusted independently for the respective elements (2, 3). Alternatively, with a potential on the semiconductor substrate (10) set equal to a supply voltage or a ground potential, a crystal substrate (20) for a forwardly biased heat generating element (2) is given the polarity opposite to that of a crystal substrate (30) for a reversely biased element (3) which may imply a problem of stray capacitance.

摘要： PROBLEM TO BE SOLVED: To enable reducing in size of a transmitter and decreasing of a cost by integrating an attenuator of an optical signal with a semiconductor laser element. SOLUTION: The semiconductor laser element comprises a light source for emitting a laser beam and a modulator for modulating the beam and integrated with the light source on a semiconductor substrate, so that the attenuator for regulating the optical output of the beam is formed in a similar layer structure to the light source on the substrate. Thus, the attenuator which has heretofore been a separate component can be integrated with the laser element by applying a conventional element forming process by constituting the attenuator similarly to the light source.
