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…
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…
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…
Scalable Low-latency Optical Phase Sensor Array
Zhanghao Sun, Sunil Pai, Carson Valdez +5
Optical phase measurement is critical for many applications and traditional approaches often suffer from mechanical instability, temporal latency, and computational complexity. In…
