Designing voltage tunable single and multi-channel optical filter with 1DDPC nano-structure
An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...

متن کاملEfficient double-filtering with a single acousto-optic tunable filter.
We describe an efficient double-filtering method that uses a single acousto-optic tunable filter (AOTF) to improve the spectral resolution and intrinsic sidelobes for the spectral domain analysis systems. Double filtering with a single AOTF is realized by applying a unique feedback scheme based on the fact that incident light can be diffracted into two orthogonally polarized beams of light by a...
متن کاملMultiple-Channel Piezoelectric Actuated Tunable Optical Filter for WDM Application
Abstract—We propose new multiple-channel piezoelectric (PZT) actuated tunable optical filter based on racetrack multi-ring resonators for wavelength de-multiplexing network applications. We design tunable eight-channel wavelength de-multiplexer consisting of eight cascaded PZT actuated tunable multi-ring resonator filter with a channel spacing of 1.6nm. The filter for each channel is basically ...
متن کاملCrosstalk Analysis of an Acousto-Optic Tunable Filter Based Optical Add/Drop Multiplexer for DWDM System
Dense Wavelength Division Multiplexing (DWDM) system is limited by different impairments like optical attenuation, crosstalk, chromatic dispersion, polarization mode dispersion, Scattering etc. All of these impairments restrict the transmission distance and bandwidth. In the Present Scenario the DWDM system needs significant improvement, where analyzing the crosstalk of an Acousto-Optic Tunable...
