Wide band filter/amplifier diode optical resonant waveguide having variable step Bragg network placed waveguide and wavelength variation following derivative offset resonant reflections first/higher second optical frequency.

摘要

The optical resonant waveguide (50) has a part in a waveguide (3) between reflectors (13,40). The second network is a Bragg network with variable steps, and has a section near the first reflector and one far from it. The Bragg wavelength variation represents a network section derivative of the Bragg wavelength with respect to an offset. The offset follows continuously the resonant reflections between a first optical frequency and a second higher optical frequency.
