We proposed a new method for Non-invasive measuring of blood glucose levels by using
microsphere Stimulated Raman scattering. We show that this method can be used to measure
biological glucose levels with low power lasers. The field enhancement due to the resonance condition
of high quality factor microsphere causes to reduce stimulated Raman scattering thresholds of its
surrounding media (glucose) and hence observing stimulated Raman scattering with low power. The
results from theoretical studies indicate that the stimulated Raman signal amplitude levels produced
from the very low Glucose concentrations. By measuring the changes of the signal intensity in output
of fiber, we can determine small amount of glucose with a low power
