Patent ID: 8325773

Claim:
A system for adjusting wavelengths of light emitted from laser elements via temperature control, comprising: a substrate; a first laser element coupled to the substrate; a second laser element coupled to the substrate; a thermal-isolation mechanism, wherein the thermal-isolation mechanism is coupled to the substrate between the first laser element and the second laser element; wherein the thermal-isolation mechanism thermally insulates the first laser element from the second laser element and facilitates changing a temperature of one of the first and second laser elements while restricting a flow of heat to or from the other of the first and second laser elements to limit a change in temperature of the other of the laser elements that is caused by changing the temperature of the laser element; and a thermal-control mechanism that creates a temperature difference between the first laser element and the second laser element, thereby configuring the first laser element and the second laser element to emit different wavelengths of light.
