We report experimental demonstrations of compressive sensing with photonic systems in which the measurement matrices are implemented using speckle in multimode waveguides. We calibrate by measuring a dictionary of single frequency RF sinusoids.

A method of tuning a reconfigurable silicon photonic circuit into an arbitrary unitary operator with machine learning was proposed to bypass the traditional phase-voltage calibration process and make the prediction of applied heating voltage directly.

Metasurfaces have emerged as a powerful and versatile paradigm for making many optical devices especially optical lenses. However, the approach usually used to engineer metasurface devices assumes that neighboring elements are identical. This is not the case in general and the approach thus prevents the optimization of devices that operate away from their optimum. We propose a versatile numerical method that we call local phase method (LPM) to obtain the phase of each element within the metasurface while accounting for near-field coupling with different neighbors. The proposed local phase method paves the way to highly efficient metasurface devices including, but not limited to, deflectors, high numerical aperture concentrators, lenses, cloaks, and modulators.

Strong THz field enhances the THz transmission of photoexcited graphene, increasing carrier scattering rates. High-field also reduces the relaxation time of the photocarriers by opening up the unoccupied states, while photoexcitation retards the relaxation process.
