Measurements, simulations, and models of the point-spread function of electron-beam lithography
Nikolaj B. Hougs, Kristian S. Knudsen, Marcus Albrechtsen +3
When a sample is exposed using electron-beam lithography, the electrons scatter deep and far in the substrate, resulting in unwanted deposition of dose at both the nano- and the mi…
Multimode optomechanics with a two-dimensional optomechanical crystal
Guilhem Madiot, Marcus Albrechtsen, Clivia M. Sotomayor-Torres +2
Chip-scale multimode optomechanical systems have unique benefits for sensing, metrology and quantum technologies relative to their single-mode counterparts. Slot-mode optomechanica…
Design, fabrication, and characterization of electrostatic comb-drive actuators for nanoelectromechanical silicon photonics
Thor August Schimmell Weis, Babak Vosoughi Lahijani, Konstantinos Tsoukalas +2
Nanoelectromechanical systems offer unique functionalities in photonics: The ability to elastically and reversibly deform dielectric beams with subwavelength dimensions enable elec…
Intermodulation of optical frequency combs in a multimode optomechanical system
Ryan C. Ng, Paul Nizet, Daniel Navarro-Urrios +6
Phonons offer the possibility to connect the microwave and optical domains while being efficiently transduced with electronic and optical signals. Here, we present a multimodal opt…
Optomechanical generation of coherent GHz vibrations in a phononic waveguide
Guilhem Madiot, Ryan C. Ng, Guillermo Arregui +5
Nanophononics has the potential for information transfer, in an analogous manner to its photonic and electronic counterparts. The adoption of phononic systems has been limited, due…
Observation of strong backscattering in valley-Hall photonic topological interface modes
Christian Anker Rosiek, Guillermo Arregui, Anastasiia Vladimirova +4
The unique properties of light underpin the visions of photonic quantum technologies, optical interconnects, and a wide range of novel sensors, but a key limiting factor today is l…
Electronic-photonic circuit crossings
Babak Vosoughi Lahijani, Marcus Albrechtsen, Rasmus Christiansen +4
Electrical control of light in integrated photonics is central to a wide range of research and applications. It is conventionally achieved with thermo-optic tuning, but this suffer…
Two regimes of confinement in photonic nanocavities: bulk confinement versus lightning rods
Marcus Albrechtsen, Babak Vosoughi Lahijani, Søren Stobbe
We present a theoretical study of dielectric bowtie cavities and show that they are governed by two essentially different confinement regimes. The first is confinement inside the b…
Cavity optomechanics with Anderson-localized optical modes
Guillermo Arregui, Ryan Cecil Ng, Marcus Albrechtsen +3
Confining photons in cavities enhances the interactions between light and matter. In cavity optomechanics, this enables a wealth of phenomena ranging from optomechanically induced…
Nanometer-scale photon confinement in topology-optimized dielectric cavities
Marcus Albrechtsen, Babak Vosoughi Lahijani, Rasmus Ellebæk Christiansen +8
Nanotechnology enables in principle a precise mapping from design to device but relied so far on human intuition and simple optimizations. In nanophotonics, a central question is h…
