About this Research Topic
Fostered by ChatGPT and carbon neutralization, the next-generation optical communication systems call for transceivers with larger bandwidth, lower power consumption and smaller size. TFLN is an ideal candidate to satisfy all these critical metrics. Currently, TFLN is being transferred from research laboratories to commercial foundries for volume production with high yield and low cost. The aim of this Research Topic is to facilitate the development of TFLN platform and its applications.
This Research Topic will focus on the latest progress in the thin film lithium niobate (TFLN) platform. It will bring together recent developments in TFLN nanofabrication, passive devices (TFLN polarization rotators, 90-deg hybrid, mode filters, etc.), III–V heterogeneous integration, electro-optic and acousto-optic modulators, piezo-optomechanics, frequency combs, visible wavelength applications, quantum sources, optical parametric applications, and so forth.
