We demonstrate C-band subpicosecond wavelength conversion over > 100nm, exploiting four wave mixing in a high index doped silica waveguide spiral of 45cm, showing a +16.5dB net gain for a 40W peak pump power.
We demonstrate broadband low power supercontinuum generation in arsenic sulphide (As2S3) tapered fiber nanowires with an effective area ~0.8 μm2 and nonlinearity γ = 12,400 W-1 km-1. Simulations showed good agreement between theory and experiment.
We present the first system penalty measurements for all-optical wavelength conversion via four wave mixing in an integrated, CMOS compatible, ring resonator, obtaining < 0.3 dB system penalty at 2.5Gb/s for ∼22dBm average pump power.
A supercontinuum spectrum of more than 300nm is obtained at 1550nm and 1290nm using doped-silica glass, 45cm long, integrated spiral waveguides. Different dynamics near two distinct zero dispersion wavelengths are observed and explained theoretically.
Sub-ps pulse compression is demonstrated by using an integrated nonlinear chirper based on an integrated, low loss, low dispersion, high index glass (Hydex??) spiral waveguide. Compressions of 40% are demonstrated for peak power around 100 W.
