Abstract :
Small-signal frequency modulation response and chirp characteristics of a tunable, optically-pumped 1.6 μm vertical cavity surface emitting laser (VCSEL) based on microelectromechanical at wavelength tuning are presented for the first time. From the measurements the linewidth enhancement factor αH has been derived and is discussed.
