Castor Optics is a Montreal-based leading manufacturer of specialized optical fiber components and engines. Castor use their expertise to develop and manufacture custom couplers and/or assembly for the best of the customer's application.

Since 2013, it has been a key strategic partner of Thorlabs developing the double-clad fiber couplers (DCFC) family. Castor was founded by Caroline Boudoux, Nicolas Godbout, Normand Brais, and Alex Cable to commercialize the innovative fiber coupler technology developed in the laboratories of Prs. Caroline Boudoux and Nicolas Godbout. The team at Castor works closely with Thorlabs' Canada office to bring to market a broad range of fiber-based optical components for next-generation medical imaging devices and advanced instrumentation for use in the physical sciences.

Caroline Boudoux



Caroline is a professor of engineering physics at Polytechnique Montréal. She earned her PhD from the MIT in 2007. Her areas of research include biomedical imaging, optical coherence tomography, confocal and nonlinear microscopy, and endoscopic imaging.

Nicolas Godbout



Nicolas is a professor at École Polytechnique Montréal. He obtained his PhD from Polytechnique Montréal in 2000. Following this, he led the optical design team at ITF Optical Technologies. His research interests include nonlinear and quantum optics, fiber lasers, fiber-optic design and fabrication, characterization.

Alex Cable


Mr. Cable, founder and President of Thorlabs, has grown Thorlabs from a fledgling basement business founded in 1989 to a successful global industry leader that offers extensive photonics product from small optical and optomechanical components to cutting-edge instrumentation and integrated photonic solutions such as novel biomedical imaging systems. 

Kathy Beaudette

Product Line Manager

Kathy obtained her PhD from Polytechnique Montréal in 2017 during which she developed, in collaboration with the Wellman Center for Photomedicine (Boston, MA), a DCF-based system combining OCT and laser coagulation. Prior to joining Castor, she was a Senior OCT Engineer at Alcon Laboratories.


Lucas Majeau

Operations Manager


Lucas joined Castor right after obtaining his engineering degree from Polytechnique Montréal, where he led a team of designers to create a fiber optics-based sensory glove discussed at TEDx Montréal and at Radio-Canada.

Normand Brais

President of the Board


Normand Brais holds a PhD in Nuclear Engineering from Polytechnique Montréal. He has founded several successful technological companies in fields as various as atmospheric pollution reduction for power plants, biomass combustion systems, air and surface disinfection for hospitals and buildings by germicidal UV irradiation, and anti-legionellosis water treatment.

Catherine Sanschagrin

Fiber Optics Technician

Catherine earned a technical diploma in physics engineering from Cégep de la Pocatière followed by an engineering degree from Polytechnique Montréal. She joined Castor with more than five years of experience in supply chain management and fiber optics assembly.
