Introduction to VCSEL optical modules
A VCSEL module (Vertical-Cavity Surface-Emitting Laser module) is a compact laser assembly that integrates a VCSEL gain chip, optics and packaging into a ready-to-use light source. Basic device properties and generally applicable cavity design rules are introduced. The following description of emission characteristics is restricted to high e±ciency VCSELs that apply. They are widely scalable in power and offer a robust and economic solution for many new. n, RIN RIN IPIN BW n Here RIN is a parameter characterizing the laser RIN noise measured in dB/Hz.
