Abstract
A medical sensor is described. In an example, the medical sensor includes a nanoscale tapered waveguide attached to a substrate. The nanoscale tapered waveguide includes a nanoscale channel that receives fluid and an excitation light and that outputs a response light. The excitation light propagates through the fluid. A receiving channel of the nanoscale channel is configured as a waveguide that receives and guides the excitation to a linearly tapered channel of the nanoscale channel. The linearly tapered channel has three dimensional linear tapering that focuses the excitation light guided from the receiving channel into an optical response channel of the nanoscale channel. In turn, the optical response channel is configured as a waveguide that outputs a response light in response to the excitation light focused from the linearly tapered channel. The response light corresponds to a response of an analyte of the fluid present in the optical response channel.
