ABSTRACT:
A tunable multisection laser of the invention includes an active layer (C2) which is thicker in a phase tuning section (S3) and in a grating section (S2) including a Bragg distributed reflector (R) having a controllable equivalent pitch than it is in a light amplification section (S1). The invention is particularly applicable to making components for telecommunications by means of optical fibers.
