“…On the theoretical side there has also recently been considerable attention to tuning (Sharkawy et al 2005) and sensing aspects (Kurt and Citrin 2005a, b;Prasad et al 2006;Xiao and Mortensen 2006;Mortensen et al 2006;Mortensen and Xiao 2007;Xiao and Mortensen 2007). In passing, we note that somewhat parallel to the above development there has been Fig.…”

Optical techniques are finding widespread use in analytical chemistry for chemical and bio-chemical analysis. During the past decade, there has been an increasing emphasis on miniaturization of chemical analysis systems and naturally this has stimulated a large effort in integrating microfluidics and optics in lab-on-a-chip microsystems. This development is partly defining the emerging field of optofluidics. Scaling analysis and experiments have demonstrated the advantage of microscale devices over their macroscopic counterparts for a number of chemical applications. However, from an optical point of view, miniaturized devices suffer dramatically from the reduced optical path compared to macroscale experiments, e.g. in a cuvette. Obviously, the reduced optical path complicates the application of optical techniques in lab-on-a-chip systems. In this paper we theoretically discuss how a strongly dispersive photonic crystal environment may be used to enhance the lightmatter interactions, thus potentially compensating for the reduced optical path in lab-on-a-chip systems. Combining electromagnetic perturbation theory with full-wave electromagnetic simulations we address the prospects for achieving slow-light enhancement of Beer-Lambert-Bouguer absorption, photonic band-gap based refractometry, and high-Q cavity sensing.

“…With inverse opal photonic crystals, refractive index variation of the order of 0.02 and having a sensitivity of 10 À3 could be measured [117]. Even though there are other photonic crystal refractive index sensors that have a sensitivity of 10 À5 based on the super prism effect [118], the optical measurements are more complicated than those described in [117].…”

“…It is the major technology for the structure design of PC in the optical signal processing with certain direction or frequency forbidden or transmitted [4,5] . Due to these characteristics, PC has been applied in a wide variety of areas, such as PC lasers [6] , filters [7] , fibers [8] , sensors [9] , antennas, laser diodes, and so on. A very promising application of photonic bandgap (PBG) structures is to improve the performance of waveguides.…”
