A system for optical spectroscopy through a probe implanted in a tissue is provided. The system includes a light collecting probe comprising a waveguide formed by a single optical fiber and having a proximal end and a distal end, the proximal end being formed with a taper along which at least one optical window is positioned, wherein light entering at an axial section of the taper generates a specific subset of guided modes defined by the diameter of the single optical fiber at the axial section, the guided modes propagating toward the distal end of the waveguide and generating an output at the distal end of the waveguide; a demultiplexer configured to receive outputs provided by the light collecting probe and discriminate the outputs based on their modal content of origin; and a detector configured to detect the discriminated outputs.

System and method for axially resolved light collection from a tapered waveguide

A multi-point light-delivering device, comprising a waveguide carrying light along a longitudinal axis and including multiple optical windows, through which the carried light is out-coupled from the waveguide. The waveguide comprises a tapered region along which the optical windows are distributed, wherein each optical window out-couples a specific subset of propagating modes of the carried light, to which the optical window is matched.
