ABSTRACT:
An external cavity laser apparatus includes a wavelength tuning element mounted to a carrier on the apparatus's platform. Thermal control of the platform sets an initial position of the carrier and tuning element, from which independent tuning of the element can be achieved for wavelength tuning. The carrier is formed of a liquid crystal polymer that thermally isolates the tuning element from this platform, for such independent thermo-optical tuning. The liquid crystal polymer may match the coefficient of thermal expansion of the carrier to that of the platform. The support further includes embedded electrodes, either within or on the outer surface of the carrier, which can couple from the tuning element to the controller, where in some examples such coupling is direct and without use of additional electrical traces or wire bonds.
