  We investigate the observable consequences of Planck scale effects in the
advanced gravitational wave detector by polymer quantizing the optical field in
the arms of the interferometer. We construct a new set of polymer-modified
creation and annihilation operators to quantize the optical field. Employing
these polymer-modified operators, we obtain the fluctuations in the radiation
pressure on the end mirrors and the number of output photons. We compare our
results with the standard quantization scheme and corrections from the
Generalized Uncertainty Principle.
