BPN703: Directly Modulated High-Speed nanoLED Utilizing Optical Antenna Enhanced Light Emission

Project ID BPN703
Website
Start Date Tue 2013-Jan-29 16:53:21
Last Updated Fri 2014-Jan-31 16:49:35
Abstract Coupling an optical antenna to a nanoscale light emitter has been shown to increase the spontaneous emission rate by compensating for the large size mismatch between the emitter and emission wavelength. This spontaneous emission rate enhancement has been predicted to be as large as several orders of magnitude, easily surpassing the stimulated emission rate and enabling high direct modulation bandwidths. The aim of this project is to utilize this concept to demonstrate a directly modulated nanoscale semiconductor light emitting diode (nanoLED) with modulation speeds in excess of 10s of GHz, exceeding the bandwidth of semiconductor lasers. Unlike lasers, such nanoLEDs are also inherently low-power and do not require minimum threshold current density for operation and are therefore a promising light generating source for use, for example, in intra-chip communication.
