Nonlinear wave dynamics on a chip
Matthew T. Reeves, Walter W. Wasserman, Raymond A. Harrison +7
Shallow water waves are a striking example of nonlinear hydrodynamics, giving rise to phenomena such as tsunamis and undular waves. These dynamics are typically studied in hundreds…
Fibre-coupled photonic crystal hydrophone
Lauren R. McQueen, Nathaniel Bawden, Benjamin J. Carey +3
Many applications, including medical diagnostics, sonar and navigation rely on the detection of acoustic waves. Photonic hydrophones demonstrate comparable sensitivity to piezoelec…
