  • Abstract
    Three-dimensional taper structures made from plasma-enhanced chemical vapor-deposited hydrogenated amorphous silicon were evaluated by calculating the deposition profiles with a line-of-sight model and the corresponding mode profiles with a full-vectorial mode solver. The tapers were fabricated with shadow-masks made from KOH-etched Si wafers, and with the tapers light was coupled into 500-nm-wide photonic wires from lensed fibers.
