Enhancement in Light Extraction Efficiency of GaN-Based Light-Emitting Diodes Using Double Dielectric Surface Passivation
GaN Light-Emitting Diode (LED) Al2O3 PEALD Passivation Double Dielectric Stack Layer
2013/1/30
SiO2Al2O3 double dielectric stack layer was deposited on the surface of the GaN-based light-emitting diode (LED). The double dielectric stack layer enhances both the electrical characteristics and the...
PAM-4 Signalling for Gigabit Transmission over Standard Step-Index Plastic Optical Fibre using Light Emitting Diodes
Gigabit Transmission Standard Step-Index Plastic Optical Fibre Light Emitting Diodes
2015/8/3
We show hardware-in-the-loop experiments for 1.25 Gbit/s Transmission over SI-POF over up to 75m using LEDs with predistorted PAM4 signalling and fractionally-spaced equalisation.
