Abstract

A potentially implantable semiconductor-laser-based sensor is demonstrated to be feasible for glucose detection at concentrations found in the human blood. In the system, the monochromatic, linearly polarized light from a diode laser is directed into an external cavity with a second diode laser at the far end. The cavity is filled with a glucose solution of varying physiological concentrations. The interference of the rotated, polarized light from the first diode laser with that of the second laser is monitored by a photodiode, forming an optoelectronic pair with the first diode laser. A variation in glucose concentration of 0.1 to 0.3 g/dl results in a 5% variation in the photodiode current. This variation is sufficient to provide feedback to an insulin pump.
