在垂直腔面发射激光器（VCSEL）中实现了亚飞秒焦耳级的偏振反转。使用两个正交偏振的注入光脉冲进行VCSEL的全光触发器操作。实现最小开关功率的两个注入脉冲的最佳波长不同，并且对应于激光器的两个偏振态的激射波长。注入脉冲的脉宽/开关频率依赖性表明，在1 ns scin 500 MHz处获得最小开关能量。开关能量达到了0.3fJ，开关频率达到了10 GHz。
Subfemtojoule polarization bistable switching in a vertical-cavity surface-emitting laser (VCSEL) is experimentally demonstrated. All-optical flip-flop operation of the VCSEL was performed using two orthogonally polarized injection light pulses. The optimum wavelengths of the two injection pulses for achieving minimum switching power were different and corresponded to the lasing wavelengths of the two polarization states of the laser. The pulse width/switching frequency dependence of the injection pulses showed that a minimum switching energy was obtained at 1ns∕500MHz. A record low switching energy of 0.3fJ has been achieved as well as a record high switching frequency of 10GHz.
