P08 – Tunable Guided-mode resonance filter using Spacetime Periodic Structure

Khorrami Y., Fathi D., Razmjooei N., Rumpf R. C.

We present a tunable planar guided-mode resonance (GMR) filter using time-varying permittivity along grating nanobars. Results show that the effective medium concept in the temporal state is exactly the same as the spatial state. Furthermore, the structure has spatial periodicity to save the resonance peak of the passive GMR in addition to the temporal periodicity […]
