Paper Abstract

We propose and demonstrate a novel polarization- and wavelength-independent digital electro-optic switch in Ti:LiNbO3 with switching voltages of ±32 at 1.55 μm wavelength. This 2×2 integrated optic switch is characterized by a steplike response to the applied voltage. Switching is achieved through adiabatic mode evolution in an asymmetric waveguide junction. An average insertion loss of ~4.5 dB and polarization-independent switching with average cross talk of −12 dB are achieved. The demonstration of 1×4 polarization-independent switches with digital optical switch elements is eventually reported.
