Experimental study of transverse mode dynamics in vertical-cavity surface-emitting lasers under current modulation Vrije Universiteit Brussel
In this work we report on an experimental investigation of the nonlinear dynamics of a 850 nm multitransverse mode vertical-cavity surface-emitting laser (VCSEL) when subject to high-frequency current modulation. Different frequencies and modulation amplitudes are applied to the VCSEL. Regular periodic dynamics -with periods equal to the modulation period or twice the modulation period- and irregular pulsating dynamics are obtained. Different ...
