METHOD OF MAKING SEMICONDUCTOR RADIATOR Russian patent published in 2013 - IPC H01L33/46 

FIELD: physics.

SUBSTANCE: obtained semiconductor radiators are designed for use in medical diagnosis equipment, environmental equipment for monitoring gaseous media, fibre-optic sensors for pressure, temperature, vibration and chemical analysis of substances, liquid and gas flow rate, in communication systems and control and measuring equipment. The method involves making a semiconductor radiator in which an end face opposite the output end of an active element is connected to an external spectrum-selective reflector based on a Bragg crystal lattice, having a series of alternating parallel layers of two types of semiconductor materials. The radiator can be superluminescent, laser single-element, multielement.

EFFECT: simple technology of manufacture owing to easier and faster assembly of elements of the radiator, high radiation power while maintaining stability of the wavelength and spectral width of the output radiation during change in ambient temperature and pumping current through the active crystal, longevity and high reliability, reduced size of the radiator and low production cost thereof.
