METHOD FOR MODULATING AN OPTICALLY PUMPED, TUNABLE VERTICAL CAVI TY SURFACE EMITTING LASER (VCSEL)

摘要

A method for modulating the output of an optically pumped, tunab le VCSEL (5). Two approaches are disclosed. In a first approach, the output of the VCSEL (5) is modulated by modulating the pump laser (100). In a second approach, the output of the VCSEL (5) is modulated by modulating a voltage applied across the active region.
