Bloch surface waves on a fiber tip
Résumé
We introduce a nano-optical platform based on Bloch surface waves (BSWs)
capable of exploiting the entire cleaved end facet of a multicore
optical fiber. Interconnecting various fiber cores with BSWs directly at
the end of a multicore fiber opens the perspective of highly compact
complex optical functionalities for the design of “lab on fiber”
devices. In counterpart, optical fibers provide a unique opportunity to
obtain turnkey nano-optical functions addressing a vast application
domain ranging from telecommunications to medical sensing. To show the
full potential of our platform, we demonstrate a multiplexing function
between three fiber cores.
