The integration of microfluidics and photonic biosensors has allowed achievement of
several laboratory functions in a single chip, leading to the development of photonic lab-on …

The flat tip of an optical fiber is a unique and unconventional platform for micro and
nanotechnologies. The small cross‐section and large aspect ratio of the fiber provide an …

We report on the first demonstration of a proof-of-principle optical fiber 'meta-tip', which
integrates a phase-gradient plasmonic metasurface on the fiber tip. For illustration and …

Focused ion beam (FIB) technology has become a promising technique in micro-and nano-
prototy** due to several advantages over its counterparts such as direct (maskless) …

We report on a novel design for the fabrication of ultrabright bowtie nanoaperture antenna
(BNA) probes to breach the intrinsic trade-off between power transmission and field …

Near-field scanning optical microscopy (NSOM) offers high optical resolution beyond the
diffraction limit for various applications in imaging, sensing, and lithography; however, for …

We propose a new concept of fiber-integrated optical nano-tweezer on the basis of a single
bowtie-aperture nano-antenna (BNA) fabricated at the apex of a metal-coated SNOM tip. We …

We report experimental behaviors of polarization-dependent, plasmonic-enhanced
molecular fluorescence within isolated bowtie nano-apertures (BNAs) milled in aluminum …

Background The tip of an optical fiber has been considered an attractive platform in Biology.
The simple cleaved end of an optical fiber can be machined, patterned and/or …

We theoretically study plasmonic antennas featuring areas of extremely concentrated
electric or magnetic field, known as hot spots. We combine two types of electric-magnetic …
