These new serpentine As2S3 waveguides offer a nonlinear coefficient ≈1700 W-1km-1 with 5× lower propagation loss over a length of 22.5 cm which ensures the full propagation length contributes towards the nonlinear process. This reduces the peak operating power thereby allowing a ×4 increase in the data rate compared with previous results. Spectral measurements show the device operates over a span of 40 nm while system measurements show just over 1 dB of power penalty at a bit-error rate of 10-9. This is primarily due to the compact planar waveguide design which minimizes the effect of groupvelocity dispersion.6 pages"OSA will grant the authors permission to deposit the publisher’s pdf from their Optics Express articles into the repository with the proper citation (reference number or journal /volume/page/year citation)." - from email received from Authorized Agent, The Optical Society, 27/05/10optical communicationsnonlinear optical signal processingfrequency conversionintegrated optics devices2007-10-3010.1364/OE.15.0150472015-12-08
