Tuning the transmission lineshape of a photonic crystal slab guided-resonance mode by polarization control.

چکیده
We demonstrate a system consisting of a two-dimensional photonic crystal slab and two polarizers which has a tunable transmission lineshape. The lineshape can be tuned from a symmetric Lorentzian to a highly asymmetric Fano lineshape by rotating the output polarizer. We use temporal coupled mode theory to explain the measurement results. The theory also predicts tunable phase shift and group delay.

Tailoring Light with Photonic Crystal Slabs : From Directional Emission to Topological Half Charges
Photonic crystal slabs are a versatile and important platform for molding the flow of light. In this thesis, we consider ways to control the emission of light from photonic crystal slab structures, specifically focusing on directional, asymmetric emission, and on emitting light with interesting topological features. First, we develop a general coupled-mode theory formalism to derive bounds on t...
متن کاملGuided resonance in Photonic Crystals
The objective of this thesis research is to analyze the guided resonances in photonic crystal slabs. It introduces the different kinds of photonic crystals and focuses on photonic crystal slabs consisting of a square lattice of air holes. The guided resonances are created by the coupling between the guided modes above the light line and radiation modes. Specifically, we calculate the transmissi...

We present an analysis of the phase and amplitude responses of guided resonances in a photonic crystal slab. Through this analysis, we obtain the general rules and conditions under which a photonic crystal slab can be employed as a general elliptical polarization beam splitter, separating an incoming beam equally into its two orthogonal constituents, so that half the power is reflected in one p...
