INJECTION LASER WITH MODULATED EMISSION Russian patent published in 2015 - IPC H01S5/625 H01S5/32 

FIELD: electricity.

SUBSTANCE: injection laser with modulated emission based on heterostructure includes section (1), control section (2), element (3) ensuring electric isolation of first ohmic contact (4) of amplification section (1) from second ohmic contact (5) of control section (2), element (6) ensuring optic link of amplification section (1) and control section (2), optical resonator for modulation transfer function and optical resonator for closed mode. Amplification section (1) includes active zone (11) comprised by at least one quantum-well active layer in waveguide layer (12) between wide-band emitter (13) with n-type conductivity and wide-band emitter (14) of p-type conductivity, first ohmic contact (4) to wide-band emitter (14) of p-type conductivity, substrate (15), third ohmic contact (16) to substrate (15). Control section (2) includes active zone (17) comprised by at least one quantum-well active layer in waveguide layer (18) between wide-band emitter (19) with n-type conductivity and wide-band emitter (20) of p-type conductivity, second ohmic contact (5) to wide-band emitter (20) of p-type conductivity, substrate (15), third ohmic contact (16) to substrate (15).

EFFECT: possible reduction of control signal power.
