Abstract

Disclosed herein is a high speed optical transceiver module, which makes it possible to prevent a wavelength shift and thus to achieve low power and high efficiency by forming a hole with a predetermined depth in a stem heat sink for dissipating heat generated in an LD through a lower portion of a stem and putting a micro heater in the hole, thereby compensating for the temperature of the LD in order to prevent wavelength shift caused by the influence of the ambient temperature on an LD chip in a transistor outline (TO) when an un-cooled optical transceiver module is driven at low temperature and to prevent the communication from being impossible when the ambient temperature is lowered during the communication using a CWDM scheme.
