Propagation-induced limits to high harmonic generation in 3D Dirac semimetals
Jeremy Lim, Yee Sin Ang, Lay Kee Ang +1
3D Dirac semimetals (DSMs) are promising materials for terahertz high harmonic generation (HHG). We show that 3D DSMs' high nonlinearity opens up a regime of nonlinear optics where…

Highly efficient terahertz generation using 3D Dirac semimetals
Lu Wang, Jeremy Lim, Liang Jie Wong
We show that 3D Dirac semimetals are promising candidates for highly efficient optical-to-terahertz conversion due to their extreme optical nonlinearities. In particular, we predic…
