Hot-Carrier-Induced Nonlinear Optical Processes in Photonic Metamaterials
Abstract
The proposed research is organized into three main thrusts and six tasks, as outlined below:I. Hot-carrier induced nonlinear genera"tion of light in metal-EAM hybrid metamaterialsTask 1. Design and implement EAM-incorporated hybrid metamaterials with optimized hot-carrier generation rates and robust charge transfer channels.Task 2. Explore second-order parametric nonlinear processes via anis"otropic injection of hot-carriers into amorphous EAMs, enabled by a continuous wave laser.II. Employing hot-carrier momentum depend"ency to mitigate material and design limitationsTask 3. Make use of crystalline EAMs with anisotropic electron density of states to" facilitate hot-carrier-enabled nonlinear effects in metamaterials with centrosymmetric meta-atoms.Task 4. Demonstrate hot-carrier," momentum-controlled nonlinear generation of light from crystalline EAMs as a probing tool for material characterization.III. Harmonic generation and wave mixing of light enabled by hot-carrier current flowTask 5. Generation of electric current inside the EAMs through the injection and collective motion of hot carriers in electrically biased plasmonic structures and metamaterial platformsTask 6. Investigate nonlinear functionalities of electrically activated hybrid metamaterials where the inversion symmetry is disrupted by hot-carrier induced current generation
