Efficient multi-mode to single-mode fiber coupling: introduction

The coupling of the optical signal from a multi-mode to a single-mode fiber is a critical issue in application fields that involve numerical aperture optical systems and high accuracy optical characterization tools, such as astronomy and laser testing. Indeed, such multi-mode to single-mode coupling is virtually impossible without loss of spectral information while keeping an acceptable power output. These articles will be aimed at screening the possible setups for such coupling, and finding the ones that offer the best trade-off…

How to address laser spectrum analysis and signal processing in a practical way with undergraduate students?

In order to answer this question, we asked Dr. Guillermo Martin, professor at Grenoble Alpes University, which practical cases he set up to address these topics with his students. Hello Guillermo. Could you please introduce yourself and describe your professional background? I did a joint Ph.D between ENS-Cachan and the University of Madrid on the study of nonlinear optics in organic material for frequency conversion. In 2006 I joined the IPAG (Institut de Planétologie et d’Astrophysique de Grenoble) laboratory where…
