Abstract
A novel multifunctional optical device, combining optical filtering,
amplification, attenuation and switching functions in one unit, was designed and
demonstrated in covering both C- and L-bands, by taking advantage of excellent
electrooptic (EO) property in the gain media of 2.0 mol% Er3+ doped and 2.0
mol%Er3+, 5.0 mol%Yb3+ codoped lanthanum-modified lead
zirconate titanate (PLZT) ceramics. In order to optimize the multifunctional device, the
absorption and photoluminescence spectra and optical gain profiles of the core
components-optically active ceramic variable waveplates were studied experimentally,
along with the dielectric, optical, thermal and EO characterization of the typical
non-memory ceramic plates. This work has paved a way leading to a broader spectrum of
applications, specifically in constructing monolithic, array- and microchip-based
devices and systems, with erbium and other rare earth doped PLZT ceramics as both gain
media and electrically variable waveplates.
