Fabrication Development of a Large Area Grating for Out of Plane Beam Coupling
Jonathan Trisno, Tong Hua Lee, Parvathi Nair S. +5
We develop a single-layer waveguide surface grating structure to vertically couple near infrared (NIR) light at ~1.55 um wavelength from a large area (~100 um length scale) Si wave…

Wide band gap phase change material tuned visible photonics
Weiling Dong, Hailong Liu, Jitendra K Behera +6
Light strongly interacts with structures that are of a similar scale to its wavelength; typically nanoscale features for light in the visible spectrum. However, the optical respons…
