A system for optical spectroscopy through a probe (10) implanted in a tissue, the system including a light collecting probe (10) comprising a waveguide formed by a single optical fiber (11) and having a proximal end (11a) and a distal end (11b), the proximal end (11a) being formed with a taper (12) along which at least one optical window (11c) is positioned, wherein light entering at an axial section of the taper (12) generates a specific subset of guided modes defined by the diameter (a1, a2, . . . , an) of the optical fiber at that axial section, the guided modes propagating toward the distal end (11b) of the waveguide and generating an output (OUT) at the distal end of the waveguide; a demultiplexer (20) configured to receive outputs (OUT) provided by the probe (10) and discriminate the outputs (OUT) based on their modal content of origin; and a detector (30) configured to detect the discriminated outputs.
A system for optical spectroscopy through a probe (10) implanted in a tissue, said system including a light collecting probe (10) comprising a waveguide formed by a single optical fiber (11) and having a proximal end (11a) and a distal end (11b), said proximal end (11a) being formed with a taper (12) along which at least one optical window (11c) is positioned, wherein light entering at an axial section of the taper (12) generates a specific subset of guided modes defined by the diameter (a1, a2, . . . , an) of the optical fiber at that axial section, said guided modes propagating toward the distal end (11b) of the waveguide and generating an output (OUT) at the distal end of the waveguide;
A system according to any of the preceding claims, further comprising a light delivery (40) configured to introduce a secondary radiation (SR) into the tissue, the light entering the taper (12) being emitted or scattered by the tissue as a response to the secondary radiation (SR).
A system according to any of the preceding claims, wherein the detector (30) comprises a sensor (61;
A method for optical spectroscopy through a probe (10) pre-implanted in a tissue, said probe comprising a waveguide (11) formed by a single optical fiber and having a proximal end (11a) and a distal end (11b), said proximal end (11a) being formed with a taper (12) along which at least one optical window (11c) is positioned,
