Dr. Julien Boucart obtained his PhD in Physics in 1997 while at Alcatel in France, working on long wavelength VCSELs for telecommunication applications. He continued working in the field of lasers (edge emitters and VCSELs) and joined Coherent (legacy II-VI) in 2006 where he worked in several functions spanning R&D, marketing, and product engineering in various fields including biomedical, industrial, data communications and consumer electronics. Since 2017, he has led the product management of VCSELs with an emphasis on consumer, biosensing and automotive applications.
VCSELs have become the predominant source of illumination for various key applications such as data communication, and consumer electronics due to their intrinsic manufacturability advantages which allows them to be produced in high volume, at low costs with high quality. The fields of applications of VCSELs can be further expanded in the growing field of optical sensors by either expanding the wavelength range, increasing the built in functionality and increasing the peak power. In this presentation, we will present the latest develop at Coherent along those three axes: extension to SWIR wavelengths, adding functionality through bottom side emission (BSE) and achieving extremely high peak power density for long range LIDARs.
