- <p>We demonstrate theoretically that photons and acoustic phonons<br>can be simultaneously guided and slowed down in specially designed nanos-<br>tructures. Phoxonic crystal waveguides presenting simultaneous phononic<br>and photonic band gaps were designed in perforated silicon membranes<br>that can be conveniently obtained using silicon-on-insulator technology.<br>Geometrical parameters for simultaneous photonic and phononic band gaps<br>were first chosen for optical wavelengths around 1550 nm, based on the<br>finite element analysis of a perfect phoxonic crystal of circular holes. A<br>plain core waveguide was then defined, and simultaneous slow light and<br>elastic guided modes were identified for some waveguide width. Joint<br>guidance of light and elastic waves is predicted with group velocities as low<br>as c/25 and 180 m/s, respectively.</p>
