The Centre for Advanced Photonics and Process Analysis (CAPPA) was delighted to be a part of the organizing committee for the European Semiconductor Laser Workshop (ESLW), which took place on September 27th and 28th, in Tyndall National Institute. Following the tradition established in 1978, the European Semiconductor Laser Workshop (ESLW) was held in Cork, directly after the 45th European Conference and Exhibition on Optical Communication (ECOC – 2019) which took place in Dublin from September 22nd to 26th. The organizing committee included CAPPA, Cork Institute of Technology, University College Cork, Rockley Photonics and the Institute of Physics Ireland.
The workshop hosted by University College Cork, provided an informal forum for sharing the most recent results and achievements in the field of semiconductor lasers and their related devices and technology. The workshop took the form of invited talks and contributed presentations, in both oral and poster form. The workshop provided a great opportunity to find new collaborators and to strengthen existing relationships. The workshop that was made up of six sessions focused on; mode locked lasers and frequency combs, VCSELS and Quantum Dot Lasers, Neuro – inspired photonics, semiconductor laser dynamics, modelling and numerical simulations, Nano and microstructures. The workshop focused on matters including dynamical phenomena in semiconductor lasers, short and long wavelength lasers, photonic crystal semiconductor lasers, nanoscale semiconductor lasers, novel material systems, structures and technologies, short pulse lasers and mode – locked lasers, semiconductor laser comb generation, optical millimeter wave generation, semiconductor optical amplifiers, lasers for telecommunications and photonic integrated circuits.
Several team members from CAPPA had hands on roles in the conference. Dr William Whelan Curtain was part of the local organising committee for the conference. Dr Robert Sheehan gave a talk on Saturday September 28 at the Nano and microsctructures session on “Mode – Hop Suppression by Cavity – Length Engineering in Hybrid External Cavity Photonic Crystal Lasers.” Dr Tomasz Piwonski presented a poster on the conference on “Semiconductor slotted laser for optical coherence tomography.” Simone Iadanza presented a poster on “Hybrid External Cavity Lasers based on Silicon Nitride 1D Photonic Crystals for WDM and Sensing Applications.”
