VERTICALLY EMITTING LASER WITH BRAGG MIRRORS AND INTRACAVITY METAL CONTACTS Russian patent published in 2015 - IPC H01S3/00 H01S5/12 

FIELD: physics.

SUBSTANCE: inside the cavity of a vertically emitting laser with Bragg mirrors and intracavity metal contacts, between a Bragg reflector and the active region there are metal layers which are simultaneously contacts and elements of the cavity which generates the characteristic mode of the electromagnetic field, wherein the thickness of the layers of the Bragg reflector adjacent to the metal layer differs from the other layers of the Bragg reflector, which provides such a spatial structure of the characteristic mode of the electromagnetic field used for laser generation that electrical field nodes coincide with the metal layers on position, which significantly reduces light absorption by the metal layers, while providing maximum overlapping of the electric field of the characteristic mode of the laser and the active region.

EFFECT: low electrical resistance of the structure, ensuring uniform pumping electrical current and inhibiting light absorption by metal layers.
