长波长垂直腔面发射激光器开关及双稳特性
Polarization switch and bistability in long-wavelength vertical-cavity surface-emitting lasers
摘要
Abstract
To study the polarized conversion characteristics of vertical cavity surface emitting lasers ( VCSEL ) , frequency-induced polarization switching ( PS) and polarization bistability ( PB) of 1550nm VCSEL subject to orthogonal optical injection were investigated numerically by adopting extended spin -flip model.The results show that under orthogonal optical injection , PS and PB can be achieved through varying the frequency detuning between the injected field and the x linearly polarized mode in VCSEL consecutively .Furthermore, the variation of injection power and bias current have strong effects on PB width and VCSEL output emission .The controlling of frequency-induced PS and PB in a 1550nm VCSEL can be realized with appropriate selection of operating conditions .This study has reference value for the application of VCSEL in all-optical switching and all-optical memory .关键词
