Dynamics of vertical-cavity surface-emitting laser subject to optical injection and positive optoelectronic feedback
摘要
Abstract
Based on the spin-flip model（SFM）,we theoretically investigate the dynamics of a vertical-cavity surface-emitting laser（VCSEL） subject to optical injection and positive optoelectronic feedback.The results show that under the joint action of positive optoelectronic feedback and optical injection from a master VCSEL（M-VCSEL）,two polarization modes of a slave VCSEL（S-VCSEL） will show many dynamic states such as period one,period two,multi-period and chaos,and the evolution routes of these states are different for two polarization modes.Mapping of dynamic region as a function of feedback strength / and injection strength 77 is varied with frequency detuning between M-VCSEL and S-VCSEL△v（△v = v_m - v_s,where v_m and v_s are the free-running frequencies of M-VCSEL and S-VCSEL,respectively）.Compared with the case for zero or negative frequency detuning,the region of chaotic state is expanded significantly under positive△v.For a fixed△v,the influences of f andηon the chaotic bandwidth of S-VCSEL are discussed.Through selecting proper f andη,chaotic bandwidth of S-VCSEL can be improved obviously.关键词
