An optical module includes a case including an optical filter, a receptacle coupled to the case, an optical receiver, and an optical transmitter. The receptacle includes a recess formed along an outer circumferential surface thereof. The recess may be formed by a first side wall and a second side wall which face each other and a bottom surface coupling the first side wall to the second side wall. Further, at least one of the first side wall and the second side wall may include an insulating material.

Optical module and optical transceiver including the same

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.
