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. The coupler housing structure at a proximity to a first end has one of the following cross sectional configurations: a ring surrounding the longitudinal waveguides, or a structure with holes, at least one hole containing at least one of the longitudinal waveguides.
