ABSTRACT:
The invention relates to a semiconductor optical reflector serving in particular for being disposed facing an integrated laser cavity so as to feed light back into said cavity, and enable it to oscillate continuously. The reflector is made up of a plurality of cascaded Bragg reflector sections. More particularly, said sections are of the same length L and have the same coupling coefficient, and the length L of each pair of sections is given by the following relationship:
