Negative group velocity in layer-by-layer chiral photonic crystals
Kin Hung Fung, Jeffrey Chi Wai Lee, C. T. Chan
We study the group velocity of light in layer-by-layer chiral photonic crystals composed of dielectrics and metals. Through studying the band structures with an extended-zone schem…
Realization of Woodpile Structure Using Optical Interference Holography
Yee Kwong Pang, Jeffrey Chi Wai Lee, Cheuk Ting Ho +1
We report the use of a (4+1)-beam optical interference holography technique to fabricate woodpile structures in photo-resists. The configuration consists of 4 linear polarized side…
Chiral microstructures (spirals) fabrication by holographic lithography
Yee Kwong Pang, Jeffrey Chi Wai Lee, Hung Fai Lee +3
We present an optical interference model to create chiral microstructures (spirals) and its realization in photoresist using holographic lithography. The model is based on the inte…
Polarization gaps in spiral photonic crystals
Jeffrey Chi Wai Lee, C. T. Chan
We studied the optical properties of a dielectric photonic crystal structure with spirals arranged in a hexagonal lattice. The dielectric constant of the material is 9 and the fill…
