Paper Abstract

A platform that enables optical coupling from fiber-ribbon connectors to planar lightwave circuits (PLCs) is described. Flexible optical waveguides are used to form a variable length directional coupler that inserts and extracts light from a waveguide located arbitrarily inside the chip. The contact length can be adjusted for optimal coupling allowing manufacturing variation in materials, widths and cladding thicknesses present on a chip. This approach may be ideal for packaging WDM devices as the 3dB bandwidth of the coupling covers the whole 1300 -1700 nm fiber-optic telecommunication range. Coupling length control in the range of 0.05-0.2 μm leads to maximum coupling in excess of 80% for the range of conditions investigated. Simulations of the performance are discussed and initial fabrication and optical coupling results are presented.
