A laser diode assembly capable of controlling a temperature of a laser diode chip with a high accuracy. A Peltier device (26) is mounted on a base member, and a carrier (28) is mounted on the Peltier device. On the carrier (28) are mounted the laser diode chip (30), a thermistor (62), and a relay block (64). A terminal (66) for connecting the thermistor (62) to an external circuit is provided so as to extend through the base member. The thermistor (62) and the relay block (64) are connected together by wire bonding, and the relay block (64) and the terminal (66) are also connected together by wire bonding. The laser diode assembly further includes a control circuit for controlling a driving current for the Peltier device (26) contacting with the carrier (28) so as to maintain a resistance of the thermistor (62) fixed on the carrier (28) at a constant value. <IMAGE> |
