45 GHz VCSEL with Multiple Transverse-Coupled-Cavities

Not Accessible

Your library or personal account may give you access

Abstract

We propose a VCSEL laterally coupled to multiple-cavities providing modulation bandwidth beyond the relaxation-oscillation-frequency. We show a 3dB modulation bandwidth of 45 GHz, five times greater than its conventional VCSEL fabricated on the same epi-wafer.
