All-UV written integrated glass devices including planar Bragg gratings and lasers

, 2004
One attractive route to low-cost integrated optical components is the use of direct UV writing. This technique may be applied to a wide range of materials including silica-on-silicon wafers, compound oxide glasses, directly bonded glass composites and ...

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.

Trapped modes in a waveguide with a thick obstacle

, 2004
The problem of finding necessary and sufficient condi-tions for the existence of trapped modes in waveguides has been known since 1943. [10]. The problem is the following: consider an infinite strip M in xs211D2(or an infinite cylinder with the smooth ...

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

Economy of Touch : Task‐Driven Information Selection in Electrical Impedance Tomography‐based Tactile Robotic Sensing

Advanced Intelligent Systems, EarlyView.
Electrical impedance tomography (EIT) tactile skins enable multiplexed measurements that trade sensing speed against information richness. This work introduces an economy‐of‐touch framework that treats tactile sensing as an information‐budgeting problem.
