Filed: 1985-06-26
Abstract: PURPOSE:To inhibit the change of a wavelength by holding specific conditions between the cavity length and waveguide indices of first and second layer operation sections and making the intervals of longitudinal modes smaller than a predetermined value. CONSTITUTION:A semiconductor laser is provided with two functions. First, the gain difference of a longitudinal mode is increased regularly at every other longitudinal-mode interval, and mode hopping is generated positively at regular intervals to a temperature change, etc. Consequently, length up to an internal reflection section from one end surface is represented by l1 and a waveguide index in the section by n1 and length up to the internal reflection section from the other end surface is represented by l2 and a waveguide index by n2, and the relationship of l1n1=l2n2 holds, thus manufacturing an internal interference type laser. Second, the intervals of the longitudinal mode are reduced extremely, thus inhibiting the change of a wavelength through one-time hopping to a small value. Accordingly, the whole cavity length is lengthened extremely.
