  • Dynamically tunable materials for parity-time symmetric electro-optical devices
    Patent number: 10178735
    Abstract: A device includes a light adjustment apparatus having a first material and a second material. The first material includes a first real dielectric permittivity and a positive imaginary dielectric permittivity. The second material includes a second real dielectric permittivity and a negative imaginary dielectric permittivity. The first and second materials affect the flow of light. The light adjustment apparatus includes a tunable material to enable adjustment of the dielectric permittivity of the respective materials.
