Figure 3

(a) Normalized streak-camera image of gain-switched output pulses of InGaN vertical-cavity surface-emitting laser (VCSEL) with pump power of 221.7 μW. Note the wavelength dependence of pulse widths. (b) Delay times and pulse-width values of pulses for each wavelength extracted from (a). (c) Pulse waveforms of the total spectrum, short-wavelength side and long-wavelength side of pulses with pump power of 221.7 μW. Note the overlap of pulse waveforms on short-wavelength side and those of pump pulses (system's response).
