Query: Realization of high-Q/V bichromatic photonic crystal cavities defined by
  an effective Aubry-Andr\'e-Harper potential   We report on the design, fabrication and optical characterization of
bichromatic photonic crystal cavities in thin silicon membranes, with
resonances around 1550 nm wavelength. The cavity designs are based on a
recently proposed photonic crystal implementation of the Aubry-Andr\'e-Harper
bichromatic potential, which relies on the superposition of two one-dimensional
lattices with non-integer ratio between the periodicity constants. In photonic
crystal nanocavities, this confinement mechanism is such that optimized figures
of merit can be straightforwardly achieved, in particular an ultra-high-Q
factor and diffraction-limited mode volume. Several silicon membrane photonic
crystal nanocavities with Q-factors in the 1 million range have been realized,
as evidenced by resonant scattering. The generality of these designs and their
easy implementation and scalability make these results particularly interesting
for realizing highly performing photonic nanocavities on different materials
platforms and operational wavelengths.
