Abstract
An optical device is provided that includes an optical waveguide and a tuning device. The optical waveguide has an outer transverse dimension greater than about 0.3 millimeter (mm), and includes an outer cladding, and at least two cores disposed within the outer cladding, the at least two cores being spaced apart a predetermined distance to couple light from a first core to the other core. The tuning device provides a compressive force on the optical waveguide to couple one or more optical signals from one core to another core.
