    • A package for optical components includes an inner package enclosing the optical component, and an outer package enclosing the inner package. A heater may be disposed in the inner package proximate the optical component to control its temperature, and to maintain this temperature control, the outer package creates an isolated air pocket around the inner package, which thermally insulates the inner package from the outside environment. The outer package is formed of a material having low thermal conductivity, to promote this insulating function. This package is especially useful if the optical component comprises a planar light-wave circuit (PLC), e.g. an arrayed waveguide grating (AWG), which requires tight temperature control and structural integrity to maintain the integrity of the optical paths.
    • 用于光学部件的封装包括封装光学部件的内部封装以及封装内部封装的外部封装。 加热器可以在靠近光学部件的内部包装件中设置以控制其温度,并且为了保持该温度控制,外部包装围绕内部包装形成隔离的空气袋,其将内部包装与外部环境热绝缘。 外包装由具有低导热性的材料形成,以促进该绝缘功能。 如果光学部件包括平面光波电路(PLC),例如, 阵列波导光栅(AWG),其需要严格的温度控制和结构完整性来维持光路的完整性。
