Reconfigurable Free-Space Optical Interconnects
Jaekwon Lee, Carson G. Valdez, Anne R. Kroo +2
Free-space optical interconnects can support many low-data-rate channels while avoiding the cost, energy consumption, and packaging constraints of optical waveguide- or fiber-based…
Microlens-Integrated Grating Couplers for Efficient Free-Space Coupling in Silicon Photonics
Simon A. Bongarz, Ryosuke Mashiko, Anne R. Kroo +4
Grating-coupler arrays are used to couple free-space light into photonic chips, but the space required for tapers and routing waveguides limits their optical fill factor. Microlens…
Polarization vector conjugation in a photonic integrated circuit
Anna J. Miller, Carson G. Valdez, Anne R. Kroo +5
We show how to perform polarization conjugation of light in a simple apparatus without any nonlinear optical materials, based on self-configuring Mach-Zehnder interferometers fed b…
Separating partially coherent light
Paul-Alexis Mor, Anne R. Kroo, Carson G. Valdez +9
Recent advances in optical imaging and communication increasingly involve high-dimensional, partially coherent light, creating a growing need for scalable tools to measure and mani…
Integrated Photonic Polarization Synthesizer and Analyzer
Carson G. Valdez, Anne R. Kroo, Anna J. Miller +3
Polarization-resolved control and measurement of the optical field are essential for a wide range of photonic systems, including coherent communication, polarimetric sensing, and q…
A general framework for interactions between electron beams and quantum optical systems
Jakob M. Grzesik, Aviv Karnieli, Charles Roques-Carmes +5
We provide a theoretical framework to describe the dynamics of a free-electron beam interacting with quantized bound systems in arbitrary electromagnetic environments. This expands…
Diffractive Retroreflector for Distributed Sensing
Anne R. Kroo, Olav Solgaard
We introduce a modified corner cube reflector that encodes information from passive optical sensors in its retroreflected diffraction pattern, enabling remote sensor-state measurem…
Programmable Optical Filters Based on Feed-Forward Photonic Meshes
Carson G. Valdez, Anne R. Kroo, Marek Vlk +4
We demonstrate an integrated photonic circuit based on feed forward photonic meshes that can be programmed and reconfigured to perform arbitrary spectral filter functions. We inves…
On-Chip Laser-Driven Free-Electron Spin Polarizer
Clarisse Woodahl, Melanie Murillo, Charles Roques-Carmes +3
Spin-polarized electron beam sources enable studies of spin-dependent electric and magnetic effects at the nanoscale. We propose a method of creating spin-polarized electrons on an…
Three-Wave Interaction Grating Coupler with Sub-Decibel Insertion Loss at Normal Incidence
Carson G. Valdez, Simon A. Bongarz, Anne R. Kroo +4
We report the design, fabrication in a commercial foundry, and experimental results of high-efficiency, normal incidence grating couplers for silicon photonics. We observe a maximu…
High Contrast Nulling in Photonic Meshes Through Architectural Redundancy
Carson Valdez, Zhanghao Sun, Anne R. Kroo +2
We demonstrate a silicon photonic architecture comprised of Double Mach-Zehnder Interferometers (DMZIs) designed for high-contrast photonic applications. This configuration signifi…
Universal programmable and self-configuring optical filter
David A. B. Miller, Charles Roques-Carmes, Carson G. Valdez +4
We propose an approach to integrated optical spectral filtering that allows arbitrary programmability, can compensate automatically for imperfections in filter fabrication, allows…
Subrelativistic Alternating Phase Focusing Dielectric Laser Accelerators
Payton Broaddus, Thilo Egenolf, Dylan S. Black +7
We demonstrate a silicon-based electron accelerator that uses laser optical near fields to both accelerate and confine electrons over extended distances. Two dielectric laser accel…
