Volumetric Evanescent Edge Coupling for Fiber-to-Chip Optical I/O
Hamdy Elshehaby, Omar Bakheet, Mohamed A. Swillam +1
Scaling optical input/output for co-packaged optics is limited by the fiber-to-chip interface. Conventional edge coupling offers low loss and broad bandwidth but confines channels…
Angular displacement readout of a mechanical oscillator with a guided mode resonance
Diego Torres-Barajas, Oscar Angulo, Aman R. Agrawal +2
Measuring the angular displacement of a mechanical oscillator is a ubiquitous task; however, the multimode nature of angular optomechanical coupling makes coherent signal enhanceme…
Goos-Hanchen-Shift Photonic Sensor for Nanometer-Scale Delayering and Tamper Detection in Semiconductor Packages
Mia Mohammad Shoaib Hasan, Mohamed Elkabbash
We propose a co-packaged photonic tamper sensor that detects progressive delayering and localized drilling through changes in the Goos-Hanchen (GH) shift of a reflected optical bea…
Observation of Light-Driven Levitation Near Epsilon-Near-Zero Surfaces
Maria Grazia Donato, Michael Hinczewski, Theodore Letsou +6
Optical manipulation of micro- and nanoparticles near surfaces is fundamental for applications in sensing and microfluidics, yet controlling particle-surface interactions remains c…
Metasurface-Based Dual-Basis Polarization Beam Splitter for efficient entanglement witnessing
Mohamed ElKabbash
Entanglement witnessing is essential for quantum technologies such as computing, key distribution, and networking. Conventional bulk-optics methods require sequential reconfigurati…
Inverse Drexhage effect in Epsilon-Near-Zero Substrates
Sandeep Kumar Chamoli, Mohamed ElKabbash
The Drexhage effect, caused by interference between a dipole and its image formed in a substrate, modifies the local density of optical states of quantum emitters which can either…
Metal-Optic Nanophotonic Modulators in Standard CMOS Technology
Mohamed ElKabbash, Sivan Trajtenberg-Mills, Isaac Harris +8
Integrating nanophotonics with electronics promises revolutionary applications, from LiDAR to holographic displays. Although silicon photonics is maturing, realizing active nanopho…
Measuring gravitational force from Femto-gram source masses
Ahmed Roman, Asem Hassan, Mohamed ElKabbash
Gravity is the weakest of all known forces. Measuring the force of gravity from micro and nano-scale source masses is an essential first step toward low-energy quantum gravity test…
Integrated Metasurface-based Wavelengths Division Demultiplexers
Amged Alquliah, Mohamed ElKabbash, JinLuo Cheng +2
We present a design approach for realizing on-chip wavelength division demultiplexing (WDD) schemes by integrating all-dielectric metasurfaces of TiO2 nanorod arrays into a SiN wav…
Radiative Cooling with Angular Shields: Mitigating Atmospheric Radiation and Parasitic Heating
Mohamed ElKabbash
Radiative cooling emerged as a possible sustainable solution to the energy hungry vapor compression-based cooling. However, realizing subfreezing temperatures through radiative coo…
