In this work, we reveal a metasurface-enhanced laser that overcomes a key limitation in lasers: conjugate symmetry of light’s angular momentum. We demonstrate new high-purity orbital angular momentum (OAM) states with quantum numbers reaching 100 and non-symmetric...
Face masks and hand sanitizers are essential tools to prevent the spread of COVID-19. But what if these essentials could be supercharged? HSCI researchers are developing bioengineered protective materials, including a nasal spray that could keep the virus from entering the rest...
