Paper Abstract

Long time being used in Datacom, in computer mice and cell phone, last decade VCSEL developments show that this laser source is an alternative to the long established edge emitter laser diodes (EELD), with attractive high power performance, better reliability, lower manufacturing costs and design flexibility. This paper will discuss the benefits of VCSEL compared to EELD and the importance to minimize parasitic inductance when used in LiDAR application were short pulses, high peak power are required1. A theoretical analysis will be presented to show the advantage of multijunction VCSEL with better Power Conversion Efficiency (PCE) and Brightness than single junction VCSEL.
