摘要： An optical system is provided including a light source configured to emit a light; and a polarizing splitting multiplexing device including a first prism configured to split the light into two polarized light beams having different optical path lengths, and a second prism configured to combine the two polarized light beams. The first prism includes a first reflective surface and a first polarization splitting surface facing the first reflective surface, and the second prism includes a second reflective surface and a second polarization splitting surface facing the second reflective surface.

摘要： In a semiconductor laser according to an embodiment of the present disclosure, a ridge part has a structure in which a plurality of gain regions and a plurality of Q-switch regions are each disposed alternately with each of separation regions being interposed therebetween in an extending direction of the ridge part. The separation regions each have a separation groove that separates from each other, by a space, the gain region and the Q-switch region adjacent to each other. The separation groove has a bottom surface at a position, in a second semiconductor layer, higher than a part corresponding to a foot of each of both sides of the ridge part.

摘要： A distance measurement apparatus including at least one measurement unit, in which the measurement unit includes: a voltage level converter that applies an arbitrary bias to a voltage obtained on the basis of an output from a light receiver to offset a level of the voltage; an amplifier that amplifies a voltage output from the voltage level converter; and a measurement section that measures a timing at which an output from the amplifier reaches a predetermined threshold.
