Title:

SEMICONDUCTOR LASER DEVICE

Document Type and Number:

Japanese Patent JPH06350130

Kind Code:

A

Abstract:

PURPOSE: To provide a semiconductor laser device which can superpose a high frequency on a semiconductor laser chip in an optical unit without external leakage by forming an outer frame of insulating material on the periphery of a region of a comb frame comprising the optical unit where a semiconductor laser chip is to be mounted, and mounting a semiconductor laser chip on the comb frame, directly or with a semiconductor substrate in-between.

CONSTITUTION: An optical unit 15 is secured on a printed board 16 including at least a high frequency circuit. The printed board 16 has a through hole 20 formed, and the through hole 20 is so arranged that light projected from a semiconductor laser element will pass through it. Further, the printed board 16 has a metal face 19 on its underside or inside it.
