Recent research and progress have shown that using light-emitting diodes (LEDs) as a high-speed transmitter is a promising candidate in a high-speed data system. The photonic crystal (PhC) LED (PhCLED) can improve the performance of the devices for visible light communication (VLC) due to its unique spatial and temporal management of photonic modes. In this research, the dynamic behaviors of PhCLEDs...
Negative refraction was demonstrated in the visible wavelength range by two-dimensional (2D) photonic crystals inscribed at the peripheral of a GaN-based light-emitting diode (LED). Self-collimated behaviors in TE polarization were observed in the far-field measurement.
GaN-based light emitting diodes with proper-designed photonic crystal structures as surface texturing and sidewall reflectors are fabricated to improve the collection of laterally propagated light and the directionality of the device.
