Novel tunable optical filter employing a fiber loop mirror for synthesis applications in WDM
(11/12/2001)
A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...
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 ...
Optical router for optical fiber sensor networks based on a liquid crystal cell
(09/04/2003)
Optical fiber sensor networks are evolving rapidly. They are used because of the inert nature of optical fibers allowing no electromagnetic interference and safe applications in inflammable atmospheres; other relevant ...
Synthesis of optical filters using microring resonators with ultra-large FSR
(12/06/2010)
We propose a novel synthesis method for designing flexible, tunable non-periodic filters. It is based on a building block which is presented by first time for these purposes, being the poles position tuned by means of a ...
Displays and Photonics Application Group Activities
(06/01/2004)
Displays and Photonics Application Group (GDAF) is devoted to design and development of passive and active devices and sensors for their applications in WDM networks, CWDM, POF, and RF over fiber networks using different ...
Design and tolerance analysis of a router with an amplified resonator and Bragg gratings
(04/20/2000)
A novel ring resonator configuration with Bragg gratings is presented. The stability of this configuration is studied by a z-transform technique. A router design with a FWHM of 17 MHz, a -40-dB rejection ratio, and a 15-dB ...
Optical reconfigurable demultiplexer based on Bragg grating assisted ring resonators
(08/11/2014)
A polarization independent reconfigurable optical demultiplexer with low crosstalk between adjacent channels and high number of potential allocated channels is designed on silicon on insulator technology. On to off state ...
