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…
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…
