Abstract

Inserting a GaAs laser 10 in a GaAs disk 12, whose conductivity regions are opposed to those of laser 10, and enclosing the structure within two GaAs headers 16 and 18 bearing electrical contacts 20 and 22, enables disk 12 to serve as a heat sink and to electrically insulate laser 10 during operation.

Gallium Arsenide Laser Packaging

Inserting a GaAs laser 10 in a GaAs disk 12, whose conductivity regions are opposed to those of laser 10, and enclosing the structure within two GaAs headers 16 and 18 bearing electrical contacts 20 and 22, enables disk 12 to serve as a heat sink and to electrically insulate laser 10 during operation.

Improved heat transfer arises from the essential elements 10, 12, 16 and 18 being in contact with each other and being fabricated from the same material. Electrical insulation of laser 10 occurs, since disk 12 is reversely biased by the current provided to activate laser 10.

Contacts 20 and 22 are preferably annular. A coaxial conductor 24 of low impedance then supplies the necessary current. Aperture 26 allows coherent light from laser 10 to escape.
