    • 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.
    • 外腔激光装置包括安装在装置平台上的载体上的波长调谐元件。 平台的热控制设置载波和调谐元件的初始位置,从而可以实现元件的独立调谐用于波长调谐。 载体由液晶聚合物形成,该液晶聚合物将调谐元件与该平台热隔离,用于这种独立的热光学调谐。 液晶聚合物可以将载体的热膨胀系数与平台的热膨胀系数相匹配。 支撑件还包括在载体的外表面内或外表面上的嵌入式电极,其可以从调谐元件耦合到控制器,其中在一些示例中,这种耦合是直接的并且不使用额外的电迹线或引线键。
