Disclosed herein are structures, devices, and systems for detecting touch and force inputs at multiple sensing locations on a surface of an electronic device using waveguide-based interferometry. A laser light source, such as a VCSEL, inserts light into a waveguide positioned adjacent to the ...
1. The waveguide combiner can obtain a large FoV while keeping a large eyebox size, featuring a slim formfactor as well. Therefore, in this review paper, we focus on the emerging research trends and recent advances in waveguide-based AR displays....

Nowadays, biosensor technologies which can detect various contaminants in water quickly and cost-effectively are in great demand. Herein, we report an integrated channel waveguide-based fluorescent immunosensor with the ability to detect a maximum of 32
Two-wire waveguide-based Bragg gratings The two-wire WBGs studied in this work are introduced by periodically varying the cross-section of a single wire inside a micro-encapsulated two-wire waveguide29. The choice of end-to-end connected truncated cones in the grating structure (see Fig.2a) ...
