Dynamics of 1.55 μm Wavelength Single-Mode Vertical-Cavity Surface-Emitting Laser Output under External Optical Injection
Figure 2
(a) Measured optical spectra of the VCSEL in a free-running continuous-wave (black line with the -axis scale on the left-hand side) and gain-switched operations (blue line with the -axis scale on the right-hand side); measured (b) timing jitter and linewidth; (c) pulse width and pulse amplitude of the gain-switched VCSEL pulses under an external laser beam injection.
