Nonlinear optics in 2D materials

Cavity nonlinear optics with layered materials

Unprecedented material compatibility and ease of integration, in addition to the unique and diverse optoelectronic properties of layered materials, have generated significant interest in their utilization in nanophotonic devices. While initial nanophotonic experiments with layered materials primarily focused on light sources, modulators, and detectors, recent efforts have included nonlinear opt...

Active 2D materials for on-chip nanophotonics and quantum optics

Two-dimensional materials have emerged as promising candidates to augment existing optical networks for metrology, sensing, and telecommunication, both in the classical and quantum mechanical regimes. Here, we review the development of several on-chip photonic components ranging from electro-optic modulators, photodetectors, bolometers, and light sources that are essential building blocks for a...

Phase-matched nonlinear optics via patterning layered materials.

The ease of integration and a large second-order nonlinear coefficient of atomically thin layered two-dimensional (2D) materials presents a unique opportunity to realize second-order nonlinearity in a silicon compatible integrated photonic system. However, the phase-matching requirement for second-order nonlinear optical processes makes the nanophotonic design difficult. We show that by nano-pa...

Chapter 2 . Novel Processes and Materials for Infrared Nonlinear Optics

Optical systems such as signal processors, limiters, spatial light modulators, and optical computers require large and fast optical nonlinearities. Although free carrier-induced nonlinearities in semiconductors have the picosecond speeds required for use in many applications, they were considered too weak to be practical for optical systems applications. In our work, we have demonstrated that t...
