Photoluminescent amorphous silicon microspheres with intrinsic whispering-gallery-mode coupling and waveguide integration

Abstract On-chip silicon light sources are highly desirable for integrated photonics but remain challenging due to silicon’s indirect bandgap and low radiative efficiency. Amorphous silicon supports photoluminescence via band-tail states, yet lacks scalable cavity platforms for e...

Chemicallyand Morphologically Stable HgTe Nanorodsfor Infrared Photodetector Applications

Abstract We have developed the synthesis of HgTe branched nanorods that exhibit stable infrared (IR) photodetector performance on single-element detector (SED) substrates for more than a year without additional protective coating or packaging. For more than a year, we have been a...
