Joshua Caldwell

Professor Josh Caldwell was awarded a MURI grant from Office of Naval Research that provides up to $1.5M per year for five years to study twist optics using so-called two-dimensional materials with defined crystal misorientations, which has the potential to lead to new laser sources, compact optical components for on-chip photonics, and electro-optics.
