From: Unifying optical gain and electro-optical dynamics in Er-doped thin-film lithium niobate platform
a Photoluminescence (PL) spectrum of the Er:TFLN waveguide amplifier; b Measured total loss of amplifiers of different lengths under an input signal power of 30 μW; c Simulated optical and electrical loss with different oxide layer thicknesses; d Simulated VπL with different oxide layer thicknesses and electrode gaps; e Spectrum when a sine wave signal with an amplitude of 3.5 V is applied to the modulator.
