基于偏振旋转光反馈下的外光注入VCSEL产生高性能毫米波
Optical generation of high-quality millimeter-wave based on an optically injected VCSEL subject to polarization-rotated external optical feedback
摘要
Abstract
A scheme of optical generation of high-quality millimeter-wave based on the optically injected vertical-cavity- surface-emitting laser （VCSEL） subject to polarization-rotated optical feedback is proposed in this paper. Based on the spin-flip model （SFM）, wich ex- ternal disturbances taken into account, the performances of the millimeter-wave generated by this scheme are numerically investigated. The results show that under suitable operation conditions, a slave VCSEL （S-VCSEL） injected by a master VCSEL （M-VCSEL） will operate in a period-one （P1） oscillation state and the output optical intensity of S-VCSEL looks like being modulated by a microwave signal. By adjusting the injection strength ξi and the frequency detuning Au between S-VCSEL and M-VCSEL, a millimeter-wave, whose frequency can be continuously adjusted in a large range from 30 GHz to 60 GHz, is obtained. After introducing polarization- rotated optical feedback, the linewidth of millimeter-wave can be obviously narrowed by adjusting the feedback strength ξi and the feedback delay time T. For a millimeter-wave with a linewidth of 5.509 MHz, generated by the optically injected VCSEL, its linewidth can be reduced to 230.2 kHz under optimum feedback parameters. The results obtained in this paper are helpful for acquiring highquality millimeter-wave used in high speed Radio-over-Fiber （RoF） system关键词
