Influence of mode confinement factor on the modulation properties of the Vertical Cavity Surface Emitting VCSEL laser

Vertical cavity surface emitting laser VCSEL is currently the main solution for many technological aspects, ultrafast optical interconnecting, Gigabit Ethernet, etc. In this paper we present the simulation results by using Optiwave™ software version 7, of the effects of optical mode confinement fact...
