Title: HEATER-BASED METHOD AND APPARATUS FOR TEMPERATURE CONTROL AND OPTICAL MODULE
Abstract:
A heater-based method and apparatus for temperature control and an optical module. The heater-based temperature control method comprises: detecting the die temperature of a laser in an array waveguide grating (AWG) (S202); calculating the temperature difference between the die temperature and a set temperature (S204); and adjusting the die temperature of the AWG on the basis of the temperature difference (S206). The heater-based method for temperature control solves the problem of a heater being prone to an instantaneous current spike when adjusting the die temperature of the AWG.
