Liquid-infiltrated photonic crystals for lab-on-a-chip applications

In this paper we theoretically discuss how a strongly dispersive photonic crystals environment may be used to enhance the light-matter interactions, thus potentially compensating for the reduced optical path in typical lab-on- a-chip systems. Combining electromagnetic perturbation theory with full-wave electromagnetic simulations we address the prospects for slow-light enhancement of Beer-Lambert absorption and photonic band-gap based refractometry.
