Patent ID: 7300212

Claim:
A semiconductor optical package for optical communication comprising: a cooling plate dissipating internal heat generated from the semiconductor optical package and having one or more grooves passing through top and bottom surfaces thereof; and a housing without a butterfly structure for attachment to the semiconductor optical package having one or more slots formed on its bottom face, the housing comprising an optical transmission module resting on the cooling plate such that the respective slots thereof correspond to the respective one or more grooves in the cooling plate, and adapted for receiving one or more fasteners passing through the grooves and inserted into the slots for coupling the optical transmission module to the housing, the optical transmission module further includes a submount; a light source arranged on the submount, for generating a light signal having a predetermined wavelength; a photo diode for monitoring the intensity of the light signal generated from the light source; a thermistor positioned on one side of the submount and sensing an internal temperature of the optical transmission module; and a thermoelectric cooling device for comparing the internal temperature of the optical transmission module sensed by the thermistor with a desired temperature, and adjusting the temperature of the optical transmission module according to the comparison result.
