Description/Abstract
Broadband monolithic acousto-optic tunable filters that combine a piezoelectric transducer array and an acousto-optic interaction medium in a single crystal have been investigated. A linearly chirped acoustic superlattice with an optical tuning range of l =1.31.6 m m was formed by domain inversion in LiNbO 3 . X -propagating longitudinal acoustic waves are excited in a crossed-field scheme by a rf E y field applied to the superlattice and couple collinearly propagating e and o polarized optical modes. At l =1.319 m m and l =1.55 m m the spectral bandwidths (FWHM) were 1.54 and 2.3nm, respectively. A relative conversion efficiency of 43/ W and a maximum conversion efficiency of 51% were measured at 1.319 m m .
