Nonlinear Dynamics of Vertical-Cavity Surface-Emitting Lasers

Figure 11

Experimental LI curve of a VCSEL subject to a weak optical feedback (thick lines), to be compared with the case without optical feedback (thin line). The x-LP (y-LP) mode intensity is plotted in black (gray). The inset shows enlargement to better illustrate the channeled LI curve with multiple PS points. After [61].
