Abstract
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.
