Multi-wavelength cross-connect optical switch

   
   

A cross-connect switch for fiber-optic communication networks employing a wavelength dispersive element, such as a grating, and a stack of regular (non-wavelength selective) cross bar switches using two-dimensional arrays of micromachined, electrically actuated, individually-tiltable, controlled deflection micromirrors for providing multiport switching capability for a plurality of wavelengths. Using a one-dimensional micromirror array, a fiber-optic based MEMS switched spectrometer that does not require mechanical motion of bulk components or large diode arrays can be constructed with readout capability for WDM network diagnosis or for general purpose spectroscopic applications.

Un interruptor del cruz-conectar para las redes de comunicaciones fiber-optic que empleaban un elemento dispersivo de la longitud de onda, tal como una rejilla, y un apilado (no-longitud de onda selectiva) de interruptores regulares de la barra cruzada que usaban órdenes de dos dimensiones de micromachined, los micromirrors eléctricamente actuados, individual-individually-tiltable, controlados de la desviación para proporcionar la capacidad de la conmutación del multiport para una pluralidad de longitudes de onda. Usando un arsenal unidimensional del micromirror, un MEMS basado fiber-optic cambió el espectrómetro que no requiere el movimiento mecánico de componentes a granel o los órdenes grandes del diodo se pueden construir con la capacidad de la lectura para la diagnosis de la red del WDM o para los usos espectroscópicos de fines generales.
