Optics 2025-01-22 v1 Applied Physics

Abstract

We report the fabrication of an 8-meter-long thin-film lithium niobate (TFLN) optical true delay line (OTDL) using the photolithography-assisted chemomechanical etching (PLACE) technique, showing a low transmission loss of 0.036 dB/cm in the conventional telecom band.
