    摘要： Disclosed herein is a laser diode module having a thermoelectric cooling element, a laser diode, and a thermistor in a housing. The thermoelectric cooling element has a first surface and a second surface between which heat exchange is performed. The first surface is in close contact with an inner surface of the housing. A base is provided on the second surface in close contact therewith. A laser carrier and a thermistor carrier are provided on the base in close contact therewith. The laser diode and the thermistor are provided on the laser carrier and the thermistor carrier in close contact therewith, respectively. A portion of the base in the vicinity of the laser carrier is thermally connected to the housing by a metal plate, for example, thereby allowing high-precision temperature control of the laser diode.

    摘要： The invention provides an optical modulator wherein appearance of radiation mode light can be suppressed to improve performances as a device. The optical modulator includes a multiplexing waveguide which in turn includes two input waveguides to which propagation lights from a linear waveguide are inputted, a waveguide coupling element, and two output waveguides. The width of the waveguide coupling element on the input side is greater than the total width of the two input waveguides, and the width of the waveguide coupling element on the output side is greater than the total width of the two output waveguides. The device of the present invention is applied typically to an optical communication system.
