Integral active element for transmitting optical modules

With the development of injection semiconductor lasers (ISL) that generates electromagnetic energy in the optical range, a possibility of miniaturization of data transmission and processing systems operating at frequencies of 1014 Hz and higher has emerged. The current state of solid-state laser technology makes it possible to talk about modulation frequencies up to 30 GHz. It gives the possibility of development of optical microwave modulators, and providing radio transmitting devices of the optical range with a basic element base. In the present work, a prototype of a new optoelectronic device is proposed, that combines two generator elements in a single package, providing simultaneous generation of a carrier and modulating oscillations. In such a device, microwave modulation of the ISL occurs based on internal physical mechanisms, as a result of coupling between the generating crystals. The design of a multifunctional optoelectronic device and its operating principle are discussed.
