A Topological View on Optical and Phononic Fabry–Perot Microcavities through the Su–Schrieffer–Heeger Model

open access: yesApplied Sciences, 2018
Advances in nanofabrication technologies have enabled the study of acoustic wave phenomena in the technologically relevant GHz–THz range. First steps towards applying concepts from topology in nanophononics were made with the proposal of a new ...

Input-output relations for a 3-port grating coupled Fabry-Perot cavity [PDF]

open access: yes, 2005
We analyze an optical 3-port reflection grating by means of a scattering matrix formalism. Amplitude and phase relations between the 3 ports, i.e. the 3 orders of diffraction are derived.

Resonance-enhanced spectral funneling in Fabry–Perot resonators with a temporal boundary mirror

open access: yesNanophotonics, 2022
A temporal boundary refers to a specific time at which the properties of an optical medium are abruptly changed. When light interacts with the temporal boundary, its spectral content can be redistributed due to the breaking of continuous time ...
