Description

Khadga Thakuri and seven colleagues engineer deliberate flaws into layered light crystals to steer what colors pass through. Their photonic crystals stack organic semiconductor cavities between silver mirrors. A perfect stack blocks a band of light outright. One cavity built at a different size breaks the pattern on purpose.

Simulations and bench tests agree: the odd cavity plants a defect state inside the blocked band. At certain sizes that state merges with the band edge, and light slips through or gets shut out more sharply. The authors outline uses in filters and switches, where a single tuned flaw rewrites the transmission spectrum.
