Photonic component technology currently represents a strong vector for innovation in several high-end applications in various industries, ranging from biomedical sensing to advanced laser manufacturing. In the past decade, ultrafast laser processing of dielectric materials has become a dominant research technique that has enabled the engineering of complex photonic functions with unmatched precision in common transparent materials like bulk glass samples and optical fibers. Many photonic components traditionally processed using ultraviolet light, such as fiber and volume Bragg gratings, can now be fabricated with much better performances by using infrared femtosecond lasers that take advantage of the nonlinear multiphoton absorption process. In order to bring such ultrafast laser processing technology to an industrial level, we need to address the remaining scientific and technological challenges, for example mitigating the photoinduced losses resulting from ultrafast laser processing. Well supported by Teraxion, a world-leading player in the fiber Bragg grating industry, the proposed CRD project aims at further developing the ultrafast laser processing of transparent materials achieved by the applicant during the past ten years to be able to produce high performances photonic components. Through a strongly interactive joint development initiative that will leverage the R&D capabilities of both organizations, the proposed CRD project will pursue the paramount technology development required to promote femtosecond laser structured photonic components to the market.
