Next-generation interferometry with gauge-invariant linear optical scatterers
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +2
Measurement technology employing optical interference phenomena such as a fringe pattern or frequency shift has been evolving for more than a century. The systems are being designe…

Scalar computational primitives with perturbative phase interferometry
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +1
We describe how weak phase modulations applied to classical coherent light in specially modified linear interferometers can be used to perform primitive computational tasks. Instea…

Grover-Sagnac interferometer
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +2
We demonstrate a nontraditional design of the Sagnac interferometer by replacing the commonly used beam splitter with a linear-optical Grover multiport. This substitution creates a…
