Self-optimization of optical confinement in ultraviolet photonic crystal slab laser [PDF]
, 2005 We studied numerically and experimentally the effects of structural disorder on the performance of ultraviolet photonic crystal slab lasers. Optical gain selectively amplifies the high-quality modes of the passive system.

High-Q impurity photon states bounded by a photonic-band-pseudogap in an optically-thick photonic-crystal slab [PDF]
, 2012 We show that, taking a two-dimensional photonic-crystal slab system as an example, surprisingly high quality factors (Q) over 10^5 are achievable, even in the absence of a rigorous photonic-band-gap.

Shifting beams at normal incidence via controlling momentum-space geometric phases
Nature Communications, 2021 Light beams can undergo small shifts due to interesting physical phenomena at interfaces. Here, the authors design a photonic crystal slab that enables a large lateral shift at normal incidence by engineering the light-interface interaction through the ...

Photonic band gaps and defect modes of polymer photonic crystal slabs [PDF]
, 2005 We show from the photonic band calculation and the finite difference time domain simulation that polymer photonic crystal slabs with a triangular array of air holes can exhibit complete photonic band gaps for transverse electric-like modes. A line defect

Waveguides, bends and Y-junctions with improved transmission and bandwidth in hexagon-type SOI photonic crystal slabs [PDF]
, 2005 This paper presents novel ways of implementing waveguide components in photonic crystal slabs based on silicon-on-insulator (SOI). The integration platform we consider consists of hexa¬gonal holes arranged in a triangular lattice (‘hexagon-type’ photonic
