Abstract
Anti-correlation polarization dynamics in vertical-cavity surface-emitting lasers with long external cavity has been studied experimentally. The correlations are considered in the time domain and in the spectral domain. In the time domain, with fixed optical feedback strength, the minimum cross-correlation coefficient exhibits exponential decay with the bias current. With fixed bias current, strong anti-correlation can be achieved at a certain feedback ratio. In the frequency domain, strong anti-correlation is obtained at frequencies lower than 1 GHz for all bias currents. Near the relaxation oscillation frequency good correlation is found at higher bias current but poor correlation is found at lower bias currents.
