The rate of spontaneous emission from an optical emitter can be greatly enhanced using a metallic optical antenna at the penalty of efficiency. In this paper we propose a metal-dielectric antenna that eliminates the tradeoff between spontaneous emiss

Efficient high speed nanoscale optical sources are required for low power next generation data communication. In this report, we experimentally demonstrated a waveguide coupling ratio of 85.9% for the cavity-backed slot antenna LED to a single mode I

The III–V InP/InGaAsP/InGaAs material family is important for photonic devices due to its optical emission and absorption in the 1.55 and 1.3 μm telecommunication bands for optical interconnects. However, InGaAsP/InGaAs generally suffer from relat

Efficient high-speed nanoscale optical sources are required for low-power next-generation data communication. Here we propose an integrated antenna-LED on a single-mode optical waveguide. By leveraging inverse design optimization, we achieved a waveg

We performed an end-to-end link analysis for a directly modulated optical antenna nanoLED. Using a technology node extrinsic unity current-gain frequency of 260 GHz, we simulated an end-to-end energy consumption of under 1fJ/bit up to 100Gbps.

We propose a broadband and efficient structure for single-mode spontaneous emission coupling of an electrically-injected slot antenna based nanoLED. Using FDTD simulations and inverse design, we achieved 93% waveguide coupling and 50.77% spontaneous

The rate of spontaneous emission can be enhanced using either a metallic antenna or a dielectric cavity. Here we adapt elements of both types for a novel metallo-dielectric structure that exhibits ultra-low mode volume, V eff = 4.53×10−6λ3.

Large 200-fold increase in the spontaneous emission rate is experimentally observed in an electrically-injected nanoscale LED coupled to a cavity-backed slot antenna; an important achievement toward a LED that is faster than the laser.

We propose a novel structure to efficiently couple the output of electrically injected slot antenna based nanoLEDs into a single mode waveguide. 3D FDTD simulations show it is possible to achieve 85% waveguide-coupling efficiency with a 250nm 3dB ban
