Monolithic Integration of an Electroabsorption Modulator into a GaAs-based
|Keywords: Vertical cavity Surface Emitting Laser (VCSEL),
High-frequency modulation, Semiconductor lasers, Fabri-Perot Cavities
A novel device concept of Vertical Cavity Surface Emitting Laser (VCSEL) with integrated modulator is demonstrated. Gain and absorption media are positioned in two Fabri-Perot cavities formed by three DBR stacks. Tuning relative spectral positions of two cavities resonances allows operation without optoelectronic feedback, extending modulation response well beyond optoelectronic resonance frequency.
