Active Semiconductor Metasurfaces
Metasurfaces exploit nanopatterning to engineer the light-matter interaction at subwavelength length scales. With this control, we can design optical elements that produce any desired electromagnetic waveform. Currently, our primary focus in this area concerns light-emitting metasurface devices that directly produce eneingeered waveforms such as unidirectional or focused beams. We complement these investigations with ongoing research into metasurfaces for e.g., neuromorphic vision sensors, magneto-optical traps, infrared detectors, and beam steering applications.
