Query: Invariance of waveguide grating mirrors to lateral displacement phase
  shifts   We present a method to analyse the coupling of lateral displacements in
nanoscale structures, in particular waveguide grating mirrors (WGM), into the
phase of a reflected Gaussian beam using a finite-difference time-domain
simulation. Such phase noise is of interest for using WGMs in high-precision
interferometry. We show that WGMs do not couple lateral displacements into the
phase of a reflected beam to a precision of 10^{-7} rad and that WGMs are
therefore not subject to the same stringent alignment requirements as
previously proposed layouts using diffraction gratings.
