The state‐of‐the‐art of high‐refractive‐index‐contrast single‐crystalline thin lithium niobate
(LiNbO3) films as a new platform for high‐density integrated optics is reviewed. Sub …

Optical microresonators have recently attracted growing attention in the photonics
community. Their applications range from quantum electrodynamics to sensors and filtering …

The emergence of high‐quality thin film lithium niobate on an insulator has opened up new
research opportunities in the field of integrated photonics devices. Through heterogeneous …

Nanoscale waveguides are basic building blocks of integrated optical devices. Especially,
waveguides made from nonlinear optical materials, such as lithium niobate, allow access to …

We report on sub-micrometer thick LiNbO3 films produced by an improved crystal ion slicing
and bonding technique using polymer adhesive benzocyclobutene. The latter enables to …

We show, using room temperature, high-resolution electron microscopy studies, that
implanted He in LiNbO 3 nucleates and accumulates as bubbles. These He inclusions are …

In this work, multiple-energy (400 keV, 450 keV, 500 keV) He ions implantation is proposed
on Ytterbium doped YGG crystal. The choice of multiple-energy could widen the barrier layer …

Rib microring resonators were fabricated via electron beam lithography and ion milling in
lithium niobate on insulator (LNOI). LNOI is a single crystalline thin film of lithium niobate …

Ion implantation is commonly utilized during the fabrication of lithium niobate (LiNbO 3)
acousto-and opto-electronic devices. Mechanistically, implantation creates material defects …

We report on the confocal Raman characterization of the micro-structural lattice changes
induced during the high-repetition rate ultrafast laser writing of buried optical waveguides in …
