设计了一种工作在太赫兹区域频率的空心光子带隙(HCP)光纤分子光调制器,并对其性能进行了评价。将加压氢分子注入新设计的耐压HCP光纤细胞中,用高重复超短脉冲激光激发氢分子的相干运动。利用连续波激光探测相干分子运动,评价了该方案在分子光调制中的可行性。研究发现,在HCP光纤中,较长的光纤长度是分子与激光束有效相互作用的必要条件。
英文摘要
A molecular optical modulator operating at a frequency in the terahertz region based on a hollow-core photonic band gap (HCP) fiber was designed and its performance was evaluated. Pressurized hydrogen molecules were injected in the newly designed pressure-resistant HCP fiber cell and coherent molecular motions of them were excited by a highly repetitive ultrashort-pulse laser. The feasibility of molecular optical modulation by this scheme was evaluated by probing the coherent molecular motion using a continuous-wave laser. It is found that a longer fiber length is necessary for efficient interaction between molecules and a laser beam in the HCP fiber.
