1. A physiologic sensor, comprising:

  • a sensor body configured for placement adjacent tissue of a patient;

    a first light emitting nanostructure device configured to emit light at a first wavelength into the tissue;

    a second light emitting nanostructure device configured to emit light at a second wavelength into the tissue, wherein the first and second light emitting nanostructure devices are stacked atop one another to substantially align an axis of emission of the first light emitting nanostructure device with an axis of emission of the second light emitting nanostructure device; and

    a light detector configured to detect the light at the first wavelength and the light at the second wavelength from the tissue.
