We experimentally demonstrate the fabrication of optical micro/nanofibers (MNFs) using chemical etching and gas-flame techniques. In the chemical etching technique, a two-step process involves 40% and 24% of hydrofluoric acid solutions for the first

We numerically report highly efficient coupling of single photons from a single dipole source (SDS) using a pair of nanostructures. The maximum coupling efficiency ({\eta}p) of 56%, into guided modes of a silica nanotip (SNT), is found when the SNT o

We demonstrate the fabrication of an optical nanofiber tip (ONFT) using a two-step chemical etching technique. This technique employs 30% and 24% hydrofluoric (HF) acid for the first and second steps, respectively. In the first step, a silica single-

We report numerically the efficient channeling of single photons from a single quantum emitter into guided modes of optical nanocapillary fibers (NCFs). The NCF is formed of a liquid core optical nanofiber with inner and outer diameters. We optimize

We experimentally demonstrate the in-situ characterization of optical micro/nano fibers (MNFs).The MNF (test fiber, TF) is positioned on a microfiber (probe fiber, PF) and simulated for the scattering loss at various PF and TF diameters. The TF is fa

We demonstrate the channeling of fluorescence photons from quantum dots (QDs) into guided modes of an optical nanofiber tip (ONFT). We deposit QDs on the ONFT using micro/nano fluidic technology. We measure the photon-counting and emission spectrum o

Background: Identification is a crucial objective in autopsies, particularly when dealing with unknown, decomposed, or mutilated bodies. Various parameters are employed to establish the identity of a human being, and among them, stature holds signifi

We demonstrate a bright and polarized fiber in-line single photon source based on plasmon-enhanced emission of colloidal single quantum dots into an optical nanofiber. We show that emission properties of single quantum dots can be strongly enhanced i

We experimentally demonstrate the integration of silicon-vacancy centers in nanodiamonds (SiV-NDs) with an optical nanofiber (ONF). We grow SiV-NDs on seed NDs dispersed on a quartz substrate using a microwave plasma-assisted chemical vapor depositio
