Spectral shaping of acousto‐optic tunable filter: A method to tune the bandwidth, wavelength, and attenuation

Abstract

In this article, we presented a method, which will allow multiple parameter control of the 3‐dB bandwidth, centre‐notch wavelength, and attenuation level in a fiber‐based acousto‐optic tunable filter. The method basically involves the variation of the interaction length, RF frequency, and RF power on a single fiber device, to achieve multiple parameter tuning of the optical filter. © 2006 Wiley Periodicals, Inc.
