Overview
abstract
A polarisation-independent electro-optically tunable wavelength filter using passive polarisation splitters and strain-induced polarisation mode conversion in LiTaO3is demonstrated. Tuning of the centre wavelength from 655 to 692nm is realised. An optical bandwidth (FWHM) of 11nm and a tuning rate of 0.4nm/ V are obtained. 1994, IEE. All rights reserved.
