NON-COOLED OPTICAL COMMUNICATION MODULE

摘要

PROBLEM TO BE SOLVED: To provide an optical communication module which can efficiently respond to a change in ambient temperature and reduce the volume and manufacturing cost of the overall optical communication module. SOLUTION: The non-cooled optical communication module comprises a flat thermistor having a positive temperature coefficient which increases the resistance with the increase of temperatures, a semiconductor chip 350 disposed on the upper surface of the thermistor 320, and a driving means for applying a predetermined voltage to the thermistor.
