Abstract
We demonstrate broadband wavelength conversion of a 40 Gb/s
return-to-zero signal using four-wave-mixing (FWM) in a dispersion
engineered chalcogenide glass waveguide. The 6 cm long planar rib
waveguide 2 μm wide was fabricated in a 0.87 μm thick film etched 350nm
deep to correspond to a design where waveguide dispersion offsets the
material leading to near-zero dispersion in the C-band and broadband phase
matched FWM. The reduced dimensions also enhance the nonlinear
coefficient to 9800 W-1km-1 at 1550 nm enabling broadband conversion in a
shorter device. In this work, we demonstrate 80 nm wavelength
conversions with 1.65 dB of power penalty at a bit-error rate of 10-9.
Spectral measurements and simulations indicate extended broadband
operation is possible.
