Low insertion loss modulator based on a vertically coupled photonic crystal resonator [PDF]

, 2012
We experimentally demonstrate a simple but more efficient technique to modulate and multiplex multiple WDM channels. Our design is based on a bus waveguide vertically coupled to multiple Photonic Crystal (PhC) resonator, each of which modulates an ...

Understanding the rich physics of light propagation in slow photonic crystal waveguides [PDF]

, 2010
Selected papers. Held as part of SPIE Photonics West 2010.We study propagation losses in slow light photonic crystal waveguides and show that dispersion engineering can reduce the loss.

1D photonic crystal filled with low-temperature plasma for controlling broadband microwave transmission

AIP Advances, 2019
A 1D plasma photonic crystal (PPC) is filled with plasmas and slab dielectrics in a large volume cylindrical glow discharge device. The parameters of the PPC are designed to meet the transmission condition of broadband microwave (1.5GHz-12GHz) according ...

Polarization mixing, bound states in a continuum, and exciton-polaritons in photonic crystal slabs by a guided-mode expansion approach [PDF]

EPJ Web of Conferences
Photonic crystal (PhC) slabs, or patterned multilayer waveguides, are known to support truly guided modes with no losses, as well as quasi-guided modes that lie in the continuum of far-field radiation.

Magic configurations in moiré superlattice of bilayer photonic crystals: Almost-perfect flatbands and unconventional localization

Physical Review Research, 2022
We investigate the physics of photonic band structures of the moiré patterns that emerged when overlapping two unidimensional photonic crystal slabs with mismatched periods. The band structure of our system is a result of the interplay between intralayer
