Abstract: A system and method for generating electrical power from a heat source utilizing both photonic and thermal conversion are disclosed. Specifically, power is generated by coupling photon converters to thermoelectric pairs in a way such that the thermoelectric pairs gain not only the charge carriers (holes and electrons) generated by the photons absorbed by the photon converters, but also the charge carriers generated by excess heat in the photon converters and an added thermal gradient generated by excess energy in the absorbed photons. Heat exchanger variations for such a system are also disclosed. Specifically, heat exchangers with and without photon emitters are disclosed and variants of refractive indices for heat exchanger systems are disclosed.

Abstract: An optical frequency modulated transmitter includes a plurality of separately phased-controlled slave lasers, the outputs of which are combined to form a single output beam of the transmitter. A master optical oscillator outputs an optical signal for injection locking the plurality of slave lasers, the optical signal being frequency modulated directly in the master optical oscillator or externally thereof.

Each of the slave lasers has an output, the outputs of which are combined to form the optical beam. The plurality of slave lasers is injection locked to an optical output of a master oscillator. The optical output of the master oscillator is frequency modulated before the optical output is applied to the plurality of lasers. Each slave laser of the plurality is phased controlled relative to other slave lasers of the plurality.
