Thanks to straight collaborations with EPFL and its customers, NOVAGAN has developed state-of-the-art technologies in epitaxy and micro-technological processing for optoelectronic devices made of GaN semiconductors. The team has more than 15 years’ experience both in epitaxy, device physics and process development of LEDs and laser diodes and has access to state-of-the-art equipments in a class 100 clean room.

NOVAGAN is the first supplier of epiwafers for the fabrication of CW blue InGaN laser diodes (LDs) and the first company to demonstrate InGaN superluminescent light emitting diodes (SLEDs) emitting in the blue with its partners.

With technological and design experts, NOVAGAN can offer prototyping service and highly customizable products. We can help our customers at every step of the fabrication chain of optoelectronic device emitting from near UV to the full visible domain.

NOVAGAN has developed new fabrication methods to produce 1.5 μm LEDs and high density ultra-small pitch (<10μm) LED matrices. The technology allow the fabrication of color RGB

Staff profiles

Dr Eric Feltin

obtained his Ph. D. in Physics from the University of Nice-Sophia Antipolis in 2003. His doctoral research at CNRS-CRHEA on the growth of GaN on silicon substrates by MOVPE is one of the founding works that opened the way to the realization of light emitting diodes (LEDs) on low cost silicon substrates, a major market under tremendous development now. He also developed a new method for producing high quality free-standing GaN substrates, a critical element used for the fabrication of UV-blue laser diodes. This method is patented and currently used in the industry.

He joined the LASPE laboratory at EPFL in 2004 where he managed the growth and technology development of GaN semiconductors heterostructures with particular emphasis on microcavities, VCSELs, LEDs UV-blue laser diodes and high electron mobility transistors.

In 2009 he founded the start-up NOVAGAN which is manufacturing III-Nitride epitaxial wafers used in the fabrication of semiconductors devices such as UV-blue laser diodes and LEDs and radio frequency high power electronics (radar, telecommunications, current converter, …).

He is the author and coauthor of more than 128 publications (H factor>36) in peer-reviewed international journals and holds one patent. He participated in many FP6 and FP7 European programs (EURONIM, STIMSCATT, NITWAVE, ULTRAGAN) and H2020 project (HILICO) and 6 Swiss research projects

(2 as coordinator).
