Abstract
A multichannel optical coupler array comprises a coupler housing structure and longitudinal waveguides. At least one of the longitudinal waveguides is a vanishing core waveguide. Light traveling from a first end to a second end can escape from an inner vanishing core into a corresponding outer core proximally to an intermediate cross section, and can escape from the outer core into a combined waveguide formed by at least two neighboring outer cores proximally to the second end.
