Compact Ultra-Low Loss Optical True Delay Line on Thin Film Lithium Niobate
-
Abstract
We report the fabrication of an 8-meter-long thin-film lithium niobate optical true delay line using the photolithography-assisted chemomechanical etching technique, showing a low transmission loss of 0.036 dB/cm in the conventional telecom band.
