Our Company

Established in October 2007 by D. Battarel, K. Heggarty and J.L. de Bougrenet de la Tocnaye, HOLOTETRIX is a spin-off company of the graduate engineering school TELECOM Bretagne Optics Department. HOLOTETRIX's primary activities are the design, fabrication and commercialization of prototype Diffractive Optical Elements (DOE) and micro-optics for diverse industrial applications such as LED illumination, laser beam shaping, wavefront analyzers, etc.

HOLOTETRIX builds on more than 15 years of experience in DIFFRACTIVE OPTICS at the Optics Department of TELECOM Bretagne. In-house optical design software and high-speed parallel direct-write photoplotters make HOLOTETRIX highly competitive in terms of delay, quality and cost for the fabrication of DOE prototypes, semi-custom components and small series.

Micro-optics make possible the complex fan-in and fan-out of light. This new method to shape and deviate light with very small structures results in components which can easily be replicated and manufactured in arrays. Diffractive and refractive micro-optical elements complement the functionality and performance of traditional lenses, prisms and mirrors. Micro-optics is a key technology for meeting the needs for miniaturization, cost reduction and improved performance. Today such components are used in different applications: optical communications, LED and laser lighting, mobile computing, automotive and aerospace.

Denis Battarel : Graduate of the Ecole Superieure d'Optique in 1986. He has since then been involved in many fields of optics including microscopy, IC inspection tools, infrared systems, video projection optical engines, fiber lasers, dynamic gain equalizers for fiber optic telecommunications and miniature CMOS cameras. He has held positions of optical designer, application engineer, technical manager, R&D coordinator and site manager.

Kevin Heggarty : Graduate of the Univeristy of Cambridge in 1987, the University of Essex in 1988 and the ENST Paris in 1991. Assistant Professor at TELECOM Bretagne where he set up and runs the micro-optics research activities, he has supervised several PhD students and negociated and run numerous EC projects in this field. His research interests include non-display applications of spatial light modulators, the design and fabrication of diffractive micro-optical elements and their applications in optical telecommunications and optical information processing.

J.L. de Bougrenet de la Tocnaye : Professor at TELECOM Bretagne, head of the Optics Department, World Expert on Liquid Crystals and their applications to Information Processing, Fellow of the Optical Society of America (OSA). Founder and former CEO of OPTOGONE, laureate of Prix Special ANVAR 2001, Capital IT innovation and Cambridge Entrepreneurship Awards 2002. SPIE Technical Achievement Award 2006. Co-founder in 2006 of the company Lixys SA, specialized in composite liquid crystal shutters for welding masks.
