Abstract:
1. An optical module, comprising: an optical communication section having a semiconductor element to be subjected to temperature control disposed inside of the optical communication section; a first temperature sensor to detect an environmental temperature having a range from a first temperature to a second temperature and disposed outside of the optical communication section; a second temperature sensor to monitor a temperature of the semiconductor element; a target temperature determining unit that determines, based on the environmental temperature detected by the first temperature sensor, a target temperature which is in a predetermined operating temperature range from a third temperature to a fourth temperature; and a temperature controlling unit that controls the temperature of the semiconductor element to become the target temperature based on the determined target temperature and the temperature of the semiconductor element monitored by the second temperature sensor, wherein the first temperature is lower than the third temperature, and wherein the second temperature is higher than the fourth temperature.
