BUILT-IN HEAT TRANSFER APPARATUS FOR USE IN PLANAR OPTICAL WAVEGUIDE DEVICE MODULE

摘要

PURPOSE: A built-in heat transfer apparatus for use in planar optical waveguide device module is provided to be capable of making a thermal distribution of a planar optical waveguide device uniform by transferring the heat from a thermal source to the device, and of reducing a normal operating time of the device. CONSTITUTION: A radiation portion(24) is attached at a lower surface of a planar optical waveguide device(21), and an insulation layer(26) is coated on the lower surface(22) of the planar optical waveguide device(21). The radiation portion(24) is formed with a thin film on the lower surface(22) by a silk printing method. A pad(27) is attached to each of both ends of the radiation portion(24) so as to receive a power supply voltage through interconnection with a power line(28).
