High Efficiency III-Nitride Mirco-Light-Emitting Diodes for Display Applications
Micro-light-emitting diodes (µLEDs) with high energy efficiency are desired for a variety of display applications, including virtual reality (VR) and augmented reality (AR) near-eye displays. Although outstanding performances in different display aspects have been demonstrated with InGaN µLEDs, there are several challenges for commercialization. In this talk, two main issues, namely size-dependent efficiency and mass transfer of µLEDs, will be addressed and some promising solutions will be discussed.
Energy Efficiency Analysis of Coherent Links for Datacenters
We propose that coherent optical communication can offer energy-efficient operation in datacenters. Analysis and simulations determine optimal operating points for the laser and local oscillator (LO) and compare trade-offs in Silicon (Si) and Indium Phosphide (InP) Mach-Zehnder Modulators (MZMs) to reach pJ/b scale efficiency.
