Abstract
An optical component package, having an insulative buffer placed against the component, enclosing a first insulative cavity against a temperature-sensitive portion of the component. An outer package provides additional insulation for the component. The buffer may be formed of a soft insulative material, and pressed against the component by an inner surface of the outer package. For the PLC embodiments disclosed, the buffer is planar and includes a frame projecting from its perimeter toward the component to form the cavity. A heater may be positioned proximate the optical component to control its temperature, in which case a second buffer may be placed against the heater, enclosing a second insulative cavity against the heater, aligned with the temperature-sensitive portion of the component. The buffers and insulative cavities of the present invention provide important insulation for optical areas requiring precise temperature control for proper operation.
