ABSTRACT:
A non-electronic all-dielectric (NEAD) or non-electronic RF (NERF) front-end that exploits isolation features of photonics to eliminate metal electrodes, interconnects and the antenna. An electro-optic (EO) modulator is integrated with a dielectric resonance antenna to exploit unique isolation features of photonics. A doubly (RF and optical) resonant device design maximizes the receiver sensitivity. High-Q optical disk resonators and dielectric resonant antennas are integrated to create an efficient mixing of light and RF fields. The resulting non-electronic RF technology produces an all-dielectric RF front-end which provides complete isolation between the air interface and the ensuing electronic circuitry, enabling the creation of an RF receiver that is immune to high-power electro-magnetic pulses (EMP) and High Power Microwave (HPM) pulses. The device can also be configured as a non-intrusive field probe that co-exists with a conventional receiver and detects a EMP or HPM attack.
