    Coherent light enables length measurements of exquisite sensitivity that lie at the core of fascinating observations in fundamental and quantum physics, astrophysics, geodesy and measurement science in general.

    Novel technologies and measurement principles find application in areas that are paradigm changing not only in fundamental science, but that impact directly the global economic and political stage. Detections from ground-based gravitational-wave observatories, like LIGO and VIRGO together with measurements of their electromagnetic counterparts, have opened a new window to observe the universe’s gravitational spectrum and have reshaped astronomy and astrophysics through Gravitational Wave and Multi-Messenger observations. Plans for future observatories, such as LISA, have already started through the extremely successful LISA Pathfinder mission. Moreover, GRACE follow-on continues on GRACE’s legacy of providing information regarding climate change and our planet’s geo-dynamics through valuable observations of the Earth’s gravitational field.

    Compact and integrated photonics combined with low-loss devices and optomechanically coupled coherent light fields enable us to reach unprecedented measurement accuracies near the quantum sensing limit, which are of relevance in applications such as atom interferometers, gravimeters, and broadband inertial sensing which is crucial for autonomous navigation, particularly in GPS inaccessible environments.

    At the core of these exciting scientific endeavors lie innovative optomechanical technologies and precision measurements that make this all possible. I will talk about continuing the advances and implementation of novel optomechanical technologies in areas of precision measurements, inertial sensing and spaceborne laser-interferometric intersatellite measurements that are the focus of my research at UA.

    Speaker Bio(s): 

    Dr. Felipe Guzmán received his Ph.D. in Experimental Physics from the Max Planck Institute for Gravitational Physics and the University of Hannover, developing measurement concepts and technologies for laser interferometry in LISA, LISA Pathfinder and GRACE follow-on. Upon completion, he was awarded a NASA Postdoctoral Program (NPP) fellowship at NASA Goddard Space Flight Center and worked thereafter as a Senior Research Associate at the National Institute of Standards and Technology (NIST). Prior to joining the OSC faculty as an Associate Professor in the Fall 2018, he led a research group at the German Space Agency (DLR) in collaboration with the University of Bremen.
