An experimental comparison of nonlinear and parabolic tapered waveguide lasers and a demonstration of broad-stripe diode pumping

This paper compares the laser performance of linear and parabolic tapered waveguides in ion-exchanged Nd:Glass, finding significant advantage for the linear guides, with demonstrated adiabatic expansion to widths of 250µm.

Pancake Lenses through Curved Lamination for Compact Virtual Reality

Advanced Intelligent Systems, EarlyView.
This article presents an ultrathin VR optical system based on a 1.35 in. microdisplay, leveraging curved lamination technology. Compared to mainstream solutions, the proposed design demonstrates superior compactness (volume compression by 12%) and enhanced optical performance.

Ultrasonic Rainbow: A Meta‐Transducer for Frequency‐Selective Elastic Wave Control via Dithering‐Based Wavenumber Tuning

Advanced Intelligent Systems, EarlyView.
A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Design of an extra-low-loss broadband Y-branch waveguide splitter based on a tapered MMI structure

An optimal design for an extra-low loss buried waveguide Y-branch splitter is presented over a broadband wavelength range from 1500~1600 nm. A tapered multimode waveguide section, earlier used to reduce the excess loss, is optimized when the light ...
