We demonstrate several properties of the fractal architecture that are exploitable for optical signals processing, notably robust spatial multiplexing. Any fraction of a received signal will completely recreate a signal transmitted with a fractal architecture.
Integration of UVA-developed high power photodiodes into a novel RF package co-designed with a wide-bandwidth, fragmented aperture antenna for fiber-fed, array antenna applications.
We propose a new all-dielectric optical antenna structure with the control of its radiation direction by adjusting its geometrical parameters. As a proof, we experimentally demonstrate the dielectric optical antenna radiating in the broadside.
We experimentally demonstrate 204x spontaneous emission rate enhancement from an electrically-injected nanoLED coupled to a cavity-backed optical slot antenna. This places the spontaneous emission rate on par with the stimulated emission rate.
