High-precision spectral tuning of micro and nanophotonic cavities by resonantly enhanced photoelectrochemical etching
Eduardo Gil-Santos, Christophe Baker, Aristide Lemaitre +4
We present a simple method to tune optical micro- and nanocavities with picometer precision in the resonant wavelength, corresponding to an effective sub atomic monolayer control o…
Origin of optical losses in gallium arsenide disk whispering gallery resonators
David Parrain, Christophe Baker, Guillaume Wang +7
Whispering gallery modes in GaAs disk resonators reach half a million of optical quality factor. These high Qs remain still well below the ultimate design limit set by bending loss…
Photoelastic coupling in gallium arsenide optomechanical disk resonators
Christopher Baker, William Hease, Dac-Trung Nguyen +4
We analyze the magnitude of the radiation pressure and electrostrictive stresses exerted by light confined inside GaAs semiconductor WGM optomechanical disk resonators, through ana…
Miniature GaAs disk resonators probed by a looped fiber taper for optomechanics applications
L. Ding, P. Senellart, A. Lemaitre +3
GaAs disk resonators (typical disk size 5 \mum * 200 nm in our work) are good candidates for boosting optomechanical coupling thanks to their ability to confine both optical and me…
Damping of optomechanical disks resonators vibrating in air
D. Parrain, C. Baker, T. Verdier +5
We report on miniature GaAs disk optomechanical resonators vibrating in air in the radiofrequency range. The flexural modes of the disks are studied by scanning electron microscopy…
Critical optical coupling between a GaAs disk and a nanowaveguide suspended on the chip
C. Baker, C. Belacel, A. Andronico +6
We report on an integrated GaAs disk/waveguide system. A millimeter-long waveguide is suspended and tapered on the chip over a length of 25 μm to evanescently couple to high Q opti…
