Polarization controlled directional propagation of Bloch Surface Wave

Maria-Pilar Bernal, Hans Peter Herzig, Myun Sik Kim

Bloch surface waves (BSWs) are recently developing alternative to surface plasmon polaritons (SPPs). Due to dramatically enhanced propagation distance and strong field confinement these surface states can be successfully used in on-chip all-optical integra ...
