In this talk, I will discuss how to accelerate the design of novel metamaterials by deep learning, a subset of artificial intelligence (AI) that learns multilevel abstraction of data using hierarchically structured layers. Different from the conventional approaches, deep learning can produce fast and accurate designs without the need of case-by-case and time-consuming numerical calculations or optimizations. The results show many exciting opportunities in the areas of optical design, integration and measurements when interfacing photonics with deep learning.

We give an overview of experimental results on mid-IR femtosecond lasers and frequency combs based on polycrystalline Cr$^{2+}$: ZnS providing access to few-cycle pulses in the spectral range 2–$;3mu mathrm{m}$. We also discuss the techniques for generation of multi-octave coherent femtosecond continua with Cr$^{2+}$: ZnS lasers.

We integrate a commercial projector and camera into an optical super-resolution telescope. We employ a simple and robust image registration in combination with an incoherent Fourier Ptychography algorithm to generate resolution-enhanced images of objects.

Feature selection for polarimetric lidar material classification is explored. Experimental measurements of a diverse sample set are collected and common features emphasizing polarimetric and polarization-insensitive reflectance are calculated. Multiple classifiers are implemented. Results suggest two transmit and two return polarization states maximize classification performance.

Hydrogenation is a widely used method to improve performance of electronic devices made from silicon but much less frequently to improve corresponding optical properties. Here, we study the possible use of hydrogenation to reduce inherent optical loss in silicon. We address enablement of efficient resonance metastructures such as filters, wideband reflectors, and polarizers via successful outcomes of such experimentation. A noticeable reduction in attenuation is observed.

Synthesis and optical characterization of organogold complexes bearing substituted fluorenyl moieties are described. Certain complexes are white-light emitters. Ancillary ligands modulate rate constants of radiative and nonradiative decay, and of intersystem crossing. Density-functional theory calculations indicate emission from excited states centered on the carbanionic ligands.

We present direct measurements of the nonlinearly induced phase-shift and spectral shift via beam-deflection technique and cross-phase modulation measurements. The optical nonlinearities are enhanced due to the highly dispersive nature of epsilon-near-zero materials, which allows obtaining reduced group velocity and enhanced phase velocity.
