Novel tuneable filter based on MZ and an amplified ring resonator for OFDM networks
(1999-11-08)
A novel reconfigurable fibre based tuneable filter is proposed. The module relies on a cascaded connection of Mach-Zehnders and an amplified fibre ring resonator. MHz range adjustable FHWM bandwidths and high crosstalk are ...
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 ...
The use of tuned filters as an attenuator device of harmonics generated by multipulse converters
(2011-05-31)
The purpose of this paper is to present a computer model that enables the operation analysis of a tuned filter as an attenuator device of harmonic generated 12 and 18-pulses converters with Y-generalized differential ...

On designing linearly tunable high-Q OTA-C filters with low sensitivity
(2004-09-07)
This paper discusses a design approach for a high-Q low-sensitivity OTA-C biquad bandpass section. An optimal relationship is established between transconductances defining the differenceβ - γ in the Q-factor denominator, ...
