We report low loss silicon-on-sapphire nanowires for applications to mid infrared optics. We achieve propagation losses of < 1dB/cm at λ=1550nm, < 1.5dB/cm at λ=2080nm and < 2dB/cm at λ = 5.08 μm.
We report low loss silicon-on-sapphire nanowires for applications to mid infrared optics. We achieve propagation losses of < 1dB/cm at λ=1550nm and < 2dB/cm at λ = 5.08 μm.
We describe the fabrication of low-loss, highly flexible silica fibre nanowires which are used to characterise chalcogenide two-dimensional photonic crystal waveguide circuits and nanocavities. Localised coupling is achieved in good agreement with theory.
We demonstrate highly efficient evanescent coupling via a silica loop-nanowire, to ultra-small quantum-dot photonic-crystal cavities. It enables the tuning of both the O utilde-factor and the wavelength of the cavity mode independently.
We achieve efficient coupling to both photonic crystal waveguides and nanocavities in chalcogenide glass via low-loss, highly flexible silica fibre nanowires
We describe the fabrication of low-loss, highly flexible silica fibre nanowires which are used to characterise chalcogenide two-dimensional photonic crystal waveguide circuits. Localised coupling is achieved in good agreement with theory.
We achieve > 98% coupling efficiency (18 dB) to a highly nonlinear chalcogenide glass photonic crystal membrane waveguide via evanescent coupling from a silica fibre nanowire.
