1. A spectroscopic system that monitors oxygenation levels in biological tissue, comprising:

  • a light source having a light output;

    a predetermined length of optical fiber coupled to the light output of the light source, where the light output of the light source propagates through the optical fiber;

    an optical fiber light stabilizer provided within the optical fiber, where the light output of the light source propagates through the optical fiber light stabilizer, and where the light stabilizer redistributes modes of the light output from the light source until an equilibrium mode distribution is established in the light output propagating within the optical fiber; and

    a sensor coupled at an output of the light stabilizer, where the sensor provides the light output with the equilibrium mode distribution at an output of the spectroscopic system.
