We use a deep learning neural network to successfully indicate when an eavesdropper is present in a free-space optics ON-OFF keying communication scheme, in which the bit stream has passed through turbulence.

Light-sheet illumination improves multiphoton imaging speed. By optimizing laser pulse frequency using the quantification of photodamage in embryos, we demonstrate an order-of-magnitude signal increase in live two-photon light-sheet imaging.

We apply the self-calibrating d-scan technique to quantify the pulse train instabilities in a fiber laser with supercontinuum generation in a photonic crystal fiber (PCF). Using an all-normal dispersion PCF, stable 15-fs pulses are measured.

Utilizing the logarithmic negativity (EN) entanglement measure, we present an analysis of (optomechanical) ponderomotive entanglement generation. Results predict a max EN of about 0.2 and are highly dependent on temperature, loss, and measurement precision.
