InGaN-based Superluminescent Diodes (SLDs)

​Marry LED and LD virtues

Speckle-free + droop free + broad spectrum

A good light source for SSL+VLC

Blue SLD developed at KAUST Photonics with integrated absorber design

KAUST CEMSE EE Photonics SLD Generated​ White Light

 

KAUST CEMSE EE Photonics Enabling Data Rate

SLD shows > 800 MHz modulation bandwidth with optical power of > 10 mW, enabling a data rate of 1.3 Gbps using OOK modulation scheme.

KAUST CEMSE EE Photonics Conventional LD On Sapphire
