Optomechanics with one-dimensional gallium phosphide photonic crystal cavities

Katharina Schneider, Yannick Baumgartner, Simon Hönl +5

Gallium phosphide offers an attractive combination of a high refractive index ($n>3$ for vacuum wavelengths up to 4 μm) and a wide electronic bandgap (2.26 eV), enabling optical ca…
