Stress-controlled frequency tuning and parametric amplification of the vibrations of coupled nanomembranes
Sepideh Naserbakht, Andreas Naesby, Aurélien Dantan
Noninvasive tuning of the mechanical resonance frequencies of suspended parallel nanomembranes in various monolithic arrays is achieved by piezoelectric control of their tensile st…
Electromechanics in vertically coupled nanomembranes
Sepideh Naserbakht, Andreas Naesby, Aurélien Dantan
We investigate the electromechanical actuation of a pair of suspended silicon nitride membranes forming a monolithic optomechanical array. By controlling the membrane resonators' t…
Suspended silicon nitride thin films with enhanced and electrically tunable reflectivity
Bhagya Nair, Andreas Naesby, Bjarke R. Jeppesen +1
We report on the realization of silicon nitride membranes with enhanced and electrically tunable reflectivity. A subwavelength one-dimensional grating is directly patterned on a su…
Microcavities with suspended subwavelength structured mirrors
Andreas Naesby, Aurélien Dantan
We investigate the optical properties of microcavities with suspended subwavelength structured mirrors, such as high-contrast gratings or two-dimensional photonic crystals slabs, a…
Effects of pressure on suspended micromechanical membrane arrays
Andreas Naesby, Sepideh Naserbakht, Aurélien Dantan
The effects of pressure on micromechanical air-filled cavities made by a pair of suspended, parallel silicon nitride membranes are investigated in the free molecular and quasi-mole…
Optomechanical characterization of silicon nitride membrane arrays
Bhagya Nair, Andreas Naesby, Aurélien Dantan
We report on the optical and mechanical characterization of arrays of parallel micromechanical membranes. Pairs of high-tensile stress, 100 nm-thick silicon nitride membranes are a…
