A system and method of monitoring with temperature stabilization. The system can include a housing operably connected to a fiber optic cable that provides a light wave thereto, a relay optic for receiving the light wave and being positioned in the housing, a radiation device for processing or producing radiation in the frequency range of 10 GHz to 100 THz from the light wave and being positioned in the housing, a temperature sensor in thermal communication with the housing, and a thermal management device in thermal communication with the housing where the thermal management device adjusts a temperature within the housing based on temperature conditions measured by the temperature sensor. Other embodiments are disclosed.
