Title:
SEMICONDUCTOR LASER
Document Type and Number:
Japanese Patent JPH08330667
Kind Code:
A
Abstract:
PURPOSE: To improve the reliability of a semiconductor laser by providing the laser to be hardly damaged even by the electric noise of a reverse bias.
CONSTITUTION: The semiconductor laser 21 comprises a laser diode part 23 and a parallel diode part 25 on the same substrate 27. Its structure is preferably in a hetero structure in which the part 23 is embedded. Further, its structure is preferably in the laser 21 of a hetero structure embedded to be formed on an n-type substrate 27 in such a manner that the n-type current block layer 39 of the laser 21 is functioned as the n-type layer of the part 25.
