Re-analysis of single-mode conditions for thin-film lithium niobate rib waveguides

Results in Physics, 2021
Single-mode waveguide devices are necessary in photonic integrated circuits. Previous studies on the single-mode conditions (SMCs) of the thin film lithium niobate (TFLN) either only focus on wire waveguide, or lack comprehensive discussions on the ...

High-brightness scalable continuous-wave single-mode photonic-crystal laser

Nature, 2023
We developed large-scale photonic-crystal surface-emitting lasers with controlled Hermitian and non-Hermitian couplings inside the photonic crystal and a pre-installed spatial distribution of the lattice constant, which leads to the realization of a ...

Improved Optical Property and Lasing of ZnO Nanowires by Ar Plasma Treatment

Nanoscale Research Letters, 2019
ZnO nanowires play a very important role in optoelectronic devices due to the wide bandgap and high exciton binding energy. However, for one-dimensional nanowire, due to the large surface to volume ratio, surface traps and surface adsorbed species acts ...

Optical trapping with superfocused high-M2 laser diode beam [PDF]

, 2015
Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits.
