The hallmark of the information age is the ease with which information is stored, accessed, and shared throughout the globe. This is enabled, in large part, by the simplicity of duplicating digital information without error. Unfortunately, an ever-gr

Conference on Lasers and Electro-Optics.
We demonstrate fine phase and amplitude control of millimeter-waves, measured on-wafer using an electro-optic frequency comb, programmable spectral filter, and uni-traveling carrier photodiode. We then synthesize arbitrary waveforms with 100 GHz of b

We describe a laser-launched micro-flyer apparatus designed for spall strength measurement. The launcher uses a single pulse from a pulsed laser that is stretched in time to nominally 20 nanoseconds using an optical ring cavity, while inexpensive mul

Pressure-shear plate impact experiments generate normal and transverse particle velocities during high strain rate deformations. Traditionally, freespace lenscoupled tabletop laser interferometry techniques are used together with diffraction gratings

We present a secure communication system constructed using pairs of nonlinear photonic physical unclonable functions (PUFs) that harness physical chaos in integrated silicon micro-cavities. Compared to a large, electronically stored one-time pad, our

We demonstrate an on-chip photonic physical unclonable function using integrated evanescently coupled multimode spiral waveguides formed in silicon nitride with rich spectral features and validate it for use in an identification tagging application f

We demonstrate an innovative approach to optical ranging well beyond the receiver bandwidth using < 0.5% of Nyquist sampling while achieving picowatt minimum sensitivity. This concept shows considerable promise for LADAR/LIDAR applications.
