Simultaneous five-wavelength filtering at 2.2 nm wavelength separation using integrated-optic acousto-optic tunable filter with subcarrier detection

Abstract

We demonstrate simultaneous, independent, five-wavelength filtering using an integrated-optic acousto-optic tunable filter with a wavelength separation of 2.2 nm. The worst-case power penalty is only 2.2 dB, demonstrating the feasibility of dense multiple-wavelength operation.
