INJECTION LASER HAVING MULTIWAVE MODULATED EMISSION Russian patent published in 2015 - IPC H01S5/00 

FIELD: physics.

SUBSTANCE: injection laser having multiwave modulated emission based on a heterostructure comprises a first optical Fabry-Perot resonator bounded on one side by a first reflector and on the other side by a first distributed Bragg mirror, which forms a second reflector, a second Fabry-Perot resonator bounded on one side by the first reflector and on the other by a third reflector, an amplification section, a common amplification region, a control section, an absorption region, a first ohmic contact, a second ohmic contact, a third ohmic contact, an element which provides electrical insulation; the first optical Fabry-Perot resonator is optically coupled to the second optical Fabry-Perot resonator through part of a waveguide layer, wherein the reflectors form optical loss spectra at the output for which a given condition is satisfied. The heterostructure of the injection laser with multiwave modulated emission includes a waveguide layer enclosed between a wide-band gap emitter with p-type conductivity and a wide-band gap emitter with n-type conductivity, an active region consisting of at least one quantum-size active layer, and a substrate.

EFFECT: enabling variation of output optical power, generation wavelength, laser generation spectrum narrowing, high energy efficiency, shorter time for turning on and off emitted laser pulses.
