Abstract
Fiber optical devices formed on substrates fabricated with grooves that operate based on evanescent optical coupling through a side-polished fiber surface in each fiber involved. The fiber cladding under the side-polished fiber surface is designed to support a radial mode profile wider than a radial mode profile supported by adjacent fiber portions.
