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 ( for vacuum wavelengths up to 4 μm) and a wide electronic bandgap (2.26 eV), enabling optical ca…
Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements
Itay Shomroni, Amir Youssefi, Nick Sauerwein +5
While quantum mechanics imposes a fundamental limit on the precision of interferometric measurements of mechanical motion due to measurement backaction, the nonlinear nature of the…
Integrated gallium phosphide nonlinear photonics
Dalziel J. Wilson, Katharina Schneider, Simon Hoenl +3
Gallium phosphide (GaP) is an indirect bandgap semiconductor used widely in solid-state lighting. Despite numerous intriguing optical properties---including large and $χ^…
Highly selective dry etching of GaP in the presence of AlGaP
Simon Hönl, Herwig Hahn, Yannick Baumgartner +2
We present an inductively coupled-plasma reactive-ion etching process that simultaneously provides both a high etch rate and unprecedented selectivity for gallium phosphide (GaP) i…
Gallium phosphide-on-silicon dioxide photonic devices
Katharina Schneider, Pol Welter, Yannick Baumgartner +3
The development of integrated photonic circuits utilizing gallium phosphide requires a robust, scalable process for fabrication of GaP-on-insulator devices. Here we present the fir…
