Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator
(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 ...
Measurements on passive tunable optical filters for DWDM
(06/06/2002)
Measurements on a passive optical fibre tunable filter are presented. The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a coupler. The novel ...
Tunable optical filters using compound ring resonators for DWDM
(07/28/2003)
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 ...

Wide tunable filters using a recirculating delay line with multi-reflections
(05/01/2002)
A ring resonator with multiple reflections as a tunable filter is proposed and analyzed in this paper. A coupler and two identical Bragg gratings are used to implement the internal reflections so an active filter with a ...
Synthesis of optical filters using microring resonators with ultra-large FSR

Adaptive MCA-Matched Filter Algorithms for Binary Detection
(Universidad Nacional de Córdoba. Facultad de Matemática, Astronomía, Física y Computación, 2013)
In this work, we present a method for signal-to-noise ratio maximization using a linear filter based on minor component analysis of the noise covariance matrix. As we will see, the greatest benefits are obtained when both ...
Applications of recirculating optical configurations on filters and lasers
(07/07/2005)
In this paper, different optical configurations based on ring resonators and a reflective section in the feedback path, are proposed in order to show the feasibility of their applications in different fields. Additionally, ...
