Terahertz generation by beamlet superposition
Koustuban Ravi, Benjamin Ofori-Okai, Keith A. Nelson +1
We analytically show how a superposition of beamlets produces terahertz radiation with greater spatial homogeneity and efficiency compared to tilted-pulse-fronts generated by diffr…
THz-frequency cavity magnon-phonon-polaritons in the strong coupling regime
Prasahnt Sivarajah, Andreas Steinbacher, Blake Dastrup +1
We demonstrate the strong coupling of both magnons and phonons to terahertz (THz) frequency electromagnetic (EM) waves confined to a photonic crystal (PhC) cavity. Our cavity consi…
Terahertz-frequency magnon-phonon-polaritons in the strong coupling regime
Prasahnt Sivarajah, Jian Lu, Maolin Xiang +4
Strong coupling between light and matter occurs when the two interact strongly enough to form new hybrid modes called polaritons. Here we report on the strong coupling of both the…
THz generation using a reflective stair-step echelon
Benjamin K. Ofori-Okai, Prasahnt Sivarajah, W. Ronny Huang +1
We present a novel method for THz generation in lithium niobate using a reflective stair-step echelon structure. The echelon produces a discretely tilted pulse front with less angu…
