| Research Abstract |
The objective of this research project was to develop general-purpose quantum optics devices with rare-metal-doped optical nanofibers, such as single photon generators. However, it was revealed that fabricating nanofibers with a commercial rare-metal-doped fiber is practically difficult because of its impurities. Therefore, we decided to change our research plan to observe nonlinear light-matter interaction with low-level laser power by utilizing evanescent field exuding around a nanofiber core. To this end, we fabricated a nanofiber for 1.5-micron lasers and successfully observed saturated absorption spectra of acetylene molecules with a laser power as low as 10 mW.
