ABSTRACT:
In a semiconductor laser apparatus, a waveguide has a buried heterostructure. The confinement effect of light to the waveguide having the buried heterostructure is controlled to control laser oscillation itself. Upon execution of intensity modulation, an oscillation
on-oscillation state is selected by controlling the confinement effect of light, and upon execution of polarized wave modulation, TE or TM mode oscillation is selected by controlling the confinement effect of light.
