Singlemode-multimode-singlemode fiber structures (SMS) based on distinct sections of a pure silica multimode fiber (coreless-MMF) with diameters of 125 and 55 μm, were reported for the measurement of… (More)
Tapering single-mode-multimode-single-mode structures to enhance sensitivity is proposed and experimentally demonstrated. 50-mm-long coreless multimode fiber sections are spliced between single-mode… (More)
Non-conventional core-guided transmission windows within the visible spectral range are identified in commercial hollow-core photonic crystal fibers designed to operate at 1550 nm. These windows are… (More)
In this paper a spun elliptically birefringent photonic crystal fiber is fabricated and characterized. Its performance as a current sensor, using a polarimetric configuration, was tested and compared… (More)
We demonstrated a 650 nm wide supercontinuum generated in tapered fibres immersed in heavy water. The pump source was a low-cost diode-pumped Nd:YAG laser with a pulse width of 0.6 ns and an output… (More)
The quasi-Raman interaction between confined acoustic phonons and light in PCF is strongly altered by the introduction of a sub-wavelength hole running axially through the core. Coupling calculations… (More)
We demonstrate concentration of optical energy within a sub-wavelength air hole running the length of an optical fiber. The fiber core resembles a tiny tube with a bore diameter of 200 nm or less.
It is reported efficient energy transfer between two different photonic bandgaps of hybrid photonic crystal fibers. We experimentally observed a resonant radiation at 493 nm, which peaks at 5.6 dB… (More)
We experimentally demonstrate the cancellation of Brillouin scattering by engineering a sub-wavelength diameter silica wire with exactly opposite photo-elastic and moving-boundary contributions.
Index-guiding, hollow-core photonic crystal fibers whose core and cladding have been filled with different liquids are theoretically and experimentally demonstrated. These waveguides present a… (More)
