| Research Abstract |
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.
