We demonstrate novel cyan light-emitting-diodes (LEDs) on patterned-sapphire substrate with record-high electrical-to-optical bandwidth (0.38 GHz) among visible LEDs. 0.93Gbps error-free transmission in plastic-optical-fiber can be achieved by using such device under only 20mA bias current.
We demonstrate the performance of a novel cyan light-emitting diode (LED) on a patterned sapphire (PS) substrate as a light source for plastic optical fiber (POF) communications with the central wavelength at 500 nm. To further enhance the external quantum efficiency (EQE) and output power of this miniaturized high-speed LED, a LED with a PS substrate is adopted. Furthermore, by greatly reducing the...
