SOURCE OF ENHANCED SPONTANEOUS EMISSION Russian patent published in 2022 - IPC H01S3/67 

FIELD: fiber optic technology.

SUBSTANCE: invention relates to the field of fiber-optic sources of enhanced spontaneous emission. A source of enhanced spontaneous emission, including erbium fibers, in which population inversion is created and changed by pumping laser diodes, control and stabilization of output radiation parameters is carried out with optical splitters and photodetectors, information from which is sent to the digital signal processing and generation unit, which controls the optical power of pumping laser diodes and temperature measurement using an external temperature sensor, the presence of temperature dependences of the output radiation parameters makes it possible to stabilize and control the radiation parameters independently for several optical outputs in the operating temperature range.

EFFECT: stabilization and control of the parameters of the output optical radiation of the source of enhanced spontaneous emission independently for several optical outputs in the operating temperature range.
