Low-Loss, High-Bandwidth Fiber-to-Chip Coupling using Capped Adiabatic Tapered Fibers

We demonstrate adiabatically tapered fibers clad with a higher-index material for coupling to an on-chip waveguide. The loss from fiber to a sub-micron waveguide in a packaged device is 1.3 dB, and the 3 dB bandwidth is is 90 nm.
