Congratulations to CUDOS researchers Amol Choudhary, Elias Giacoumidis and Mike Smith and their teams for their Postdeadline papers that were presented at the Australian and New Zealand Conference on Optics and Photonics (ANZCOP) last week in Adelaide.

On-chip broadband RF photonic filters using giant Brillouin gain
A. Choudhary, I. Aryanfar, S. Shahnia, B. Morrison, K. Vu, S. Madden, B. Luther-Davies, D. Marpaung, and B. J. Eggleton
CUDOS, University of Sydney, NSW 2006, CUDOS, Laser Physics Centre, Australian National University, ACT 0200, Australia.
Abstract:An unprecedented Brillouin gain of 44dB has allowed on-chip microwave photonic filters with reconfigurable bandwidths from 30MHz upto 440MHz. The filter was tuned upto 30GHz and multiple bandpass filters are also demonstrated at different frequencies.

Record Intrachannel Nonlinearity Reduction in 40-Gb/s 16QAM Coherent Optical OFDM using Support Vector Machine based Equalization

Abstract: We experimentally demonstrate 7 dB reduction of nonlinearity penalty in 40-Gb/s 16QAM CO-OFDM at 2000 km using support vector machine regression-based equalization. This performance is by ~1.5 dB higher than full-field (single-step/size) digital back-propagation

Enhanced Stimulated Brillouin Scattering in silicon acousto-optic metamaterials
M.J.A. Smith, B.T. Kuhlmey, C. Martijn de Sterke, C. Wolff, M. Lapine and C.G. Poulton
CUDOS and IPOS, The University of Sydney, AUSTRALIA; School of Mathematical and Physical Sciences, University of Technology Sydney, AUSTRALIA.
Abstract: We propose a metamaterial based on nanoporous silicon which strongly increases the Stimulated Brillouin Scattering (SBS) response compared to bulk silicon. This paves the way towards a new generation of compact, cost-efficient silicon-based SBS devices
