Dr. Tobias Wenger is currently a NASA Postdoctoral Fellow working in the group Infrared Photonics (389G) at JPL where he is developing metasurface lenses for integration with infrared photodetectors. He received his PhD from Chalmers University of Technology, Sweden, where he worked on understanding the physical properties of plasmons in graphene.
At JPL, Tobias is applying his knowledge of subwavelength electromagnetics to design metasurface lenses for infrared wavelengths. Metasurfaces are a novel approach to optics which uses subwavelength elements for controlling the phase, amplitude and polarization of transmitted and/or reflected electromagnetic radiation. Tobias is using this to design and fabricate lenses to enhance the light collection of infrared photodetectors and subsequently enhance their sensitivity and increase their operating temperature. This will reduce the cooling needs of infrared focal plane arrays and help enable such systems for future small-satellite missions.
In his free time Tobias enjoys surfing the California coastline and occasionally hiking in the San Gabriel mountains.
