Asymmetric Transmission In Photonic Structures With Phase-Change Components

Abstract

This thesis is dedicated to all of the awesome teachers I have had in my life. Thank you so much for helping me get to where I am today. v ACKNOWLEDGEMENTS I acknowledge all of the awesome members of the Kottos lab who have helped me along the way.

VO2-hBN-graphene-based bi-functional metamaterial for mid-infrared bi-tunable asymmetric transmission and nearly perfect resonant absorption

“…This material can be a promising building block in tunable or reconfigurable metamaterial light absorbers, switches, and modulators [39][40][41][42]. As a material with nonlinear optical response under high-power operation, VO 2 can also be realized in devices with AT characteristics [43,44]. Very recently, the hybridization between the HP 2 modes of hBN and the IMT of VO 2 (i.e., hybrid HP 2 -IMT modes) has been experimentally investigated in hBN∕VO 2 heterostructures [45,46].…”
