Abstract
We demonstrate a glucose fiber sensor for measuring glucose concentration in
serum. High resolution and rapid measurement are achieved through the integration of
highly selective enzymes and heterodyne interferometry. The best resolution and
response time obtained are 0.14 mg/dL and 1.3 s, respectively. The stability of the
sensor is also verified by investigating the initial phase variation. Experimental
results show that the fiber sensor can be reused more than 10 times.
