The Role of InGaN Quantum Barriers in Improving the Performance of GaN-based Laser Diodes

By Technical Paper Link - 21 Dec, 2021 - Comments: 0

Abstract: "In this work, different aspects which have influences on device performance of blue laser diodes (LDs) when using InGaN instead of GaN as quantum barrier (QB) layers are investigated theoretically and experimentally. In the modeling calculation, it is found that the threshold current of LDs with InGaN QB layers is reduced obviously, but the slope efficiency is not largely improved... » read more

Encryption chip A team at MIT developed a new chip to lower the power consumption of public-key cryptography for IoT devices. Software execution of encryption protocols require more energy and memory space than embedded IoT sensors can typically spare, given the need to maximize battery life. The new chip is hardwired to perform public-key encryption and consumes only 1/400 as much power as... » read more
