Airguide Photonics at The Optical Networking and Communication Conference & Exhibition (OFC) 2019

Researchers from the EPSRC-funded Airguide Photonics Programme, at the University of Southampton's Optoelectronic Research Centre (ORC), will be showcasing a variety of papers and posters at the OFC 2019, San Diego, USA this week. Highlights include a tutorial on 'Advances in Hollow Optical Fibre Technologies and Applications' on Wednesday, and a postdeadline paper presentation on Thursday.

The ORC is also hosting its annual reunion on Wednesday, 6 March from 19:00-21:00 at the Royal India, 329 Market Street, San Diego. This event is open to all alumni and friends of the ORC, and sponsored by PriTel. There is no need to register.

Polarization Effects on Thermally Stable Latency in Hollow-Core Photonic Bandgap Fibres Dr Eric Numkam Fokoua reports that Hollow-Core fibres were recently demonstrated to have propagation time through them completely insensitive to changes in temperature. Here, we consider polarization dependent behaviour of these fibres and show how it can alter the fibre design.

Ultra-Broadband Bragg Scattering Four Wave Mixing in Silicon Rich Silicon Nitride Waveguides

Dr Cosimo Lacava shows the first demonstration of Bragg scattering inter-modal four-wavemixing in silicon-rich SiN waveguides. We report wavelength conversion using two spatial modes, exhibiting a maximum efficiency of -15-dB over a flat-bandwidth in excess of 30-nm.

Natsupa Taengnoi presents 'Nonlinearity Mitigation in O-Band Transmission'

We utilise the alternate mark inversion (AMI) scheme to mitigate the nonlinearity in O-band transmission. The results after transmission over 60km of SMF show that AMI outperforms the duobinary and on-off keying formats.
