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

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

Electrically driven organic laser using integrated OLED pumping
An electrically driven organic semiconductor laser is achieved by integrating a device structure that efficiently couples an organic light-emitting diode, with extremely high internal-light generation, with a polymer distributed feedback laser.

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