||Spontaneous emission has been considered slower and weaker than stimulated emission. As a
result, light-emitting diodes (LEDs) have only been used in applications with bandwidth < 1 GHz.
Spontaneous emission is inefficient because the radiating dipole is much smaller than wavelength and
such short dipoles are poor radiators. By attaching an optical antenna to the radiating dipole at the
nanoscale, the emission rate can be significantly increased enabling high modulation bandwidths
theoretically >100 GHz. This project focuses on the physical demonstration of this new type of
nanophotonic device. Current fabrication and experimental results of devices using transition metal
dichalcogenides (TMDs) as an emitter material will be presented. Fundamental limits of rate enhancement
will also be discussed.
