Electromagnetic Wave Emission from Planar and Fiber Fabry-Perot Microresonators with Multilayer and Modulated Mirrors.

Streszczenie

Planar Fabry-Perot microresonator with distributed Bragg reflector (DBR) mirrors with nonlinear semiconductor spacer of GaP is considered. Optimal DBR-GaP-DBR microstructure is suggested for THz wave efficient emission from optically pumped GaP layer. Fiber Fabry-Perot microresonator with fiber Bragg grating (FBG) reflectors is also considered. Optimal fiber microresonator structure is suggested for single longitudinal-mode radiation. For modelling the Method of Single Expression is used which is a convenient tool for solving boundary problems of electrodynamics. The method permits to solve correctly and efficiently problems of interaction of plane electromagnetic waves with multilayer and modulated media. Spectral dependences and distributions of electric field amplitude and Poynting vector in the considered microstructures are obtained.
