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： An optical isolator has a low-profile construction. Two rod-like permanent magnets are on two sides of a Faraday element in parallel to an optical axis. The two permanent magnets are sandwiched and fixed between two ferromagnetic frames each having a light path hole therein. The ferromagnetic frames are each provided with a protrusion for guiding the magnetic flux generated by the permanent magnets to the Faraday element.
