Possible realization of directional optical waveguides in photonic crystals with broken time-reversal symmetry. [PDF]
Physical Review Letters, 2005 We show how, in principle, to construct analogs of quantum Hall edge states in "photonic crystals" made with nonreciprocal (Faraday-effect) media. These form "one-way waveguides" that allow electromagnetic energy to flow in one direction only.

Ultrahigh-efficiency wavelength conversion in nanophotonic periodically poled lithium niobate waveguides [PDF]
Optica, 2018 Periodically poled lithium niobate (PPLN) waveguide is a powerful platform for efficient wavelength conversion. Conventional PPLN converters however typically require long device lengths and high pump powers due to the limited nonlinear interaction ...
