PACKAGE FOR PLANAR LIGHTWAVE CIRCUIT WITH HEAT SPREADER

摘要

PURPOSE: A package in which a planar light-wave circuit(PLC) is integrated with a heat spreader is provided to improve the operational stability of a PLC device by radiating heat from the PLC device. CONSTITUTION: A heat spreader(10) includes an upper metal film, an insulating film, a lower metal film and a protective film. The heat spreader is formed into a housing shape with a wick structure. A PLC chip(20) is attached on the upper metal film of a heat spreader. The heat spreader and the PLC chip are packaged. The insulating film is composed of ceramics.
