Welcome to VCSEL Day 2017

Welcome to VCSEL Day 2017

Dear Colleagues,

Thank you to everyone who has registered to attend and present at VCSEL Day 2017. The conference will take 08 and 09 June at Jury’s Inn in Cardiff.

These are exciting times, as emerging applications are accelerating further research and investment into VCSEL technologies globally. Our combined strengths in Europe across design, fabrication and characterisation of this versatile device, along with continued support from industry and government, places us in a unique position to lead developments in VCSEL research, innovation and commercialisation.

This year’s sessions will include VCSEL Design, Materials, Fabrication and Device Concepts. We are also pleased to include an Industry Session on the afternoon of Thursday 08 June to hear some of the latest work from companies involved in VCSELs.  Please see below for the outline agenda.We also hope that you will join us for the complimentary Conference Dinner at Cardiff Castle on the evening of Thursday 8th June.

We are still accepting registrations to attend the conference at:

Information on travel and accommodation is included at the bottom of this page for your reference.

If you have not yet specified your interest in speaking at VCSEL Day 2017, please indicate this on the registration form as soon as possible. We look forward to welcoming you in Cardiff on 08 and 09 June to share insights and ideas to further the knowledge on VCSEL technologies and applications.

With very best regards,

Conference Co-chairs: Jim Lott, Wyn Meredith and Peter Smowton


Prof. Dr. James A. Lott received his Bachelor of Science degree in electrical engineering and computer sciences from the University of California at Berkeley (USA) in 1983 and the Doctor of Philosophy from the University of New Mexico (USA) in 1993. Since his dissertation on the first AlGaInP/AlGaAs orange and red (600-690 nm) VCSELs he has worked on VCSELs and related optoelectronic and photonic materials and devices. He performed research at Sandia National Laboratories (US Department of Energy), Albuquerque, New Mexico, USA from 1988 to 1993. He was a visiting scientist at the NEC Optoelectronics Research Laboratories in Tsukuba, Japan in 1995 and at Samsung Electronics Company, Ltd. in Suwon, Republic of Korea in 1996. He is a Professor at the Technische University Berlin, Germany.

Dr. Wyn Meredith received a MA (Physics) from Cambridge University and PhD from Heriot Watt University in blue semiconductor laser development in 1997. Wyn has 19 years relevant industrial experience gained during time at Ferranti, British Telecom Research Labs, Sharp Research labs, IQE plc and as Commercial Director of Glasgow based Compound Semiconductor Technologies. 

Wyn is founding Director of the Compound Semiconductor Centre and was critically involved in defining its concept, vision and funding mechanisms. He is currently building the team necessary to execute the business plan and promote the development of Europe’s first Compound Semiconductor Technology Cluster in South Wales.

Prof. Peter Smowton received a BSc (Physics and Electronics) from UWIST and a PhD from Cardiff University on the subject of Stabilised Semiconductor Lasers for Industrial Applications in 1991. He has 26 years postdoctoral and academic experience during which time he has worked closely with many of the companies involved in the Semiconductor Industry such as Samsung, Oclaro, Diomed, Renishaw and IQE plc. He has led several multi-million collaborative research projects in the area of Compound Semiconductor device development.  Peter is an expert advisor to the UKs Engineering and Physical Sciences Research Council, has played a leading role, as program and general chair in a number of sector leading conferences such as CLEO and IEEE International Semiconductor Laser Conference and as a leading member of the IEEE Photonics Society.
