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 ...
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 ...
Time Division Multiplexing Fibre-Optic Liquid Level Sensors using a Nematic 1x2 Optical Switch
(09/01/2004)
In this paper, time division multiplexing with optical switches in a multi-sensor system for level measurements with POF is reported. POF are used in the sensor heads and as transmission media along the optical network. ...
