Resumen
The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the same optical path between the signals to be interfered (copropagating and counterpropagating ones). The filter structure allows optical integration for having higher free-spectral ranges. Simple design equations for the filter parameters and the tuning are reported. Measurements on a passive optical fiber tunable filter are presented. There is a good agreement between measurements and theory.

Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator
Vargas, Salvador; Vázquez, Carmen (11/12/2007)We propose a new synthesis method for the implementation of infinite impulse response filters, using a Sagnac interferometer within a ring resonator. This structure permits the synthesis of second-order optical functions ... -
Sagnac loop in ring resonators for tunable optical filters
Vargas, Salvador; Vázquez, Carmen; Sánchez Pena, José Manuel (08/01/2005)General filter architecture using co-and counterpropagation signals are studied. A specific configuration based on a Sagnac loop within a ring resonator is analyzed. Novel tuning, apart from conventional tuning,is achieved ...
