Temperature control of an optical device

A system for regulating a temperature of an optical device, wherein the optical device emits an optical signal at an operating wavelength, and wherein the temperature of the optical device affects the operating wavelength of the optical signal, the system comprising:

• a control circuit configured to receive a burst-mode switch signal, wherein the burst-mode switch signal switching from a first state to a second state causes the optical device to stop emitting the optical signal, and wherein the burst-mode switch signal switching from the second state to the first state causes the optical device to begin emitting the optical signal;
• and
• a time delay circuit configured to create a time delay between (i) the burst-mode switch signal switching from the second state to the first state and (ii) the optical device beginning to emit the optical signal;
• wherein the control circuit is configured to determine an amount of time that the optical device is not emitting the optical signal based on the burst-mode switch signal, wherein the control circuit is further configured to control an electric current provided to a heating element for increasing the temperature of the optical device, and wherein the control circuit is configured to control the electric current to be provided to the heating element only during the time delay.
