ABSTRACT
In this paper we present the development and implementation of a switchedquadrature optical Costas loop receiver and its performance evaluation by means of simulations and with the experimental work of an optical set up and electronic circuitry. We report as well the implementation of some of the basic building blocks that are required by both homodyne and heterodyne receivers for coherent optical communication systems (guided and unguided, i.e., optical fiber and free space optics): we present an automatic wavelength controller (AWC), an electronicallydriven state of polarization controller (ASOPC) as well as an optical phase locked loop (OPLL) for phase tracking.
Keywords: phase tracking, switchedquadratures, optical Costas loop, optical phase locked loop, optical wavelength controller, state of polarization controller.
RESUMEN
En el presente trabajo reportamos el desarrollo e implementación de un receptor basado en un lazo de Costas óptico con cuadraturas conmutadas así como la evaluación de su desempeño mediante simulaciones y a través de un montaje experimental óptico y con circuitería electrónica. Reportamos asimismo la implementación de varios de los bloques básicos que son requeridos en los receptores ópticos homodinos y heterodinos con aplicación en sistemas de comunicaciones ópticas coherentes (guiados y no guiados, es decir, por fibra óptica y por espacio libre): presentamos el control automático de longitud de onda, el controlador del estado de polarización manejado electrónicamente así como el lazo de encadenamiento de fase (PLL) óptico.
