abstract = "We propose a resonant optical Yagi-Uda nano-antenna fabricated at the end of the optical fiber probe for the sake of extracting the information of the angular directivity by absorption of directional emission as a subwavelength optical microscopy. A Yagi-Uda nano-antenna consists of a feed element surrounded by a reflector and three directors. The reflector and directors are optimized in pitches with regards to resonance of the antenna elements using the finiteelement method. We used a focused ion beam (FIB) to cut the end of the fiber probe tip away and make the flattened surface to mount the metal nano-antenna structure, followed by FIB platinum deposition patterning for the nano-antenna. To verify the characteristics of the probe based nano-antenna, directional emission from the metal slit with asymmetric metallic surface gratings is probed and detected using the photomultiplier tube. Our approach of the nano-antenna based fiber probe is suitable for scanning applications such as detection of directional emission.",
