High bandwidth traveling wave electro-optic modulator at 1μm on thin-film lithium tantalate

Published 10 Apr 2026 in physics.optics | (2604.09825v1)

Abstract: We present the first experimental demonstration of a high-bandwidth thin-film lithium tantalate (TFLT) electro-optic modulator operating at 1 μm, with a Vπ of 2.4 V, and less than 2 dB electro-optic roll-off up to 50 GHz and stable DC bias operation.
