Tailoring simultaneous photonic and phononic band gaps
TL;DR: In this article, the existence and dependence of phoxonic band gaps on the choice of lattice and unit cell is investigated. And the existence of photonic and phononic band gap opens up many possibilities for enhancing acousto-optical interactions at a common wavelength scale.
Argon plasma inductively coupled plasma reactive ion etching study for smooth sidewall thin film lithium niobate waveguide application
TL;DR: In this paper, a smooth ridge waveguide fabricated on 700 nm thickness thin film lithium niobate (TFLN) is presented, which has been done by developing and optimizing three steps of the technological process, the mask fabrication, the plasma etching, and a final cleaning wet etching step in order to remove the lithium Niobate redeposition on the side walls.

Improved tip performance for scanning near-field optical microscopy by the attachment of a single gold nanoparticle
TL;DR: In this article, the optical properties of a fiber-based probe by attachment at the tip apex of one single gold particle of 60 nm diameter were improved by a chemical procedure for the fixation of the particle on the apex of a standard tip for scanning near-field microscopy.

Optical far-field and near-field observations of the strong angular dispersion in a lithium niobate photonic crystal superprism designed for double (passive and active) demultiplexer applications
TL;DR: In this paper, a lithium niobate photonic crystal (PC) superprism was designed for double demultiplexer applications, which achieved an angular dispersion of 1.5°/nm.

TL;DR: In this paper, a parametric study of micrometric size waveguides on 700-nm thin-film lithium niobate is presented, and four different configurations in which the guiding takes place in lithium Niobate, ridge waveguide, strip-loaded waveguide and double slot waveguide are systematically investigated in order to find a good set of optimum guiding parameters for increasing light-matter interaction applications.
