Abstract:
1. An optical modulator comprising: a phase-matching optically-coupled metal-insulator-semiconductor (MIS) tunneling diode having an external bias ranging from a voltage greater than an absolute value of 0V to the absolute value of 5V; said optically-coupled metal-insulator-semiconductor (MIS) tunneling diode comprising a metal-insulator-semiconductor structure where the metal is a metal layer of 50 nm or less in thickness and a phase matching optical element; and said external bias is applied across said insulator such that it affects optical reflectance of Surface Plasmon-Polaritons (SPPs) with said optical modulator; wherein said metal-insulator-semiconductor structure comprises a gold-zirconium dioxide-indium tin oxide (Au—ZrO
