We report fabrication of the first low-loss, broadband 37-cell photonic bandgap fiber.Exploiting absence of surface modes and low cross-talk in the fiber we demonstrate mode division multiplexing over...
From scanning-electron microscope images of the cross section of a photonic-bandgap fiber (NKT Photonics’HC-1550-02) we developed a realistic model for its permittivity profile that includ...
The role of a prominent photonic bandgap (PBG) on the phenomenon of transverse localization of light in an evanescently coupled disordered one-dimensional semi-infinite lossless waveguide lattice has ...
A novel polarizer is designed by liquidfi lling in partial air-holes of a hollow-core photonic bandgap fi ber(PBGF) forming an asymmetric waveguide structur e, which leads to the vertical polarization...
We report on oscillators and amplifiers based on all-silica singlemode, large mode area photonic bandgap fibers elaborated by the modified chemical vapour deposition process.
An all-solid LMA Bragg fibre (mode area exceeding 1100μm 2 ) is presented for mid-infrared applications, based on a new design strategy that induces large differential loss between fundamental and hig...
We show that two-photon absorption (TPA) in Rubidium atoms can be greatly enhanced by the use of a hollow-core photonic bandgap fiber. We investigate off-resonant, degenerate Doppler-free TPA on the ...
To understand the loss limitations of a splice between a hollow-core fiber and a conventional fiber, we use a numerical model to calculate the expected coupling loss between the NKT Photonics’ HC-1550...
Solid photonic bandgap fibers offer distributed spectral filtering with extraordinarily high suppression. This opens new possibilities of artificially tailoring the gain spectrum of fibers. We present...
We describe the fabrication and characteristic of an all-solid photonic bandgap fiber with loss as low as 0.41dB/km at 1550nm within the first-order bandgap. The control of bandgaps,dispersion and ben...
An electrically tunable bandpass filter based on two photonic crystal fibers filled with different liquid crystals is demonstrated. Both the short-wavelength and long-wavelength edge are tuned individ...
The mode coupling properties of highly-birefringent tuneable LPGs formed in HC-PBGF are presented. The mode coupling from the fundamental core mode to higher-order guided mode of a HC-PBGF is obtained...
We review application of microstructured and photonic bandgap fibers for designing resonant optical sensors of changes in the value of analyte refractive index. This research subject has recently invo...
Using a new full-vectorial finite-difference mode solver utilizing a hexagonal Yee’s cell, we calculated the dispersion diagram of a slightly multimode (16 modes) air-core photonic-bandgap ʂ...
