Limits of slow-light in photonic crystals
Jesper Goor Pedersen, Sanshui Xiao, Niels Asger Mortensen
While ideal photonic crystals would support modes with a vanishing group velocity, state-of-the art structures have still only provided a slow-down by roughly two orders of magnitu…
Slow-light enhanced absorption for bio-chemical sensing applications: potential of low-contrast lossy materials
Jesper Pedersen, Sanshui Xiao, Niels Asger Mortensen
Slow-light enhanced absorption in liquid-infiltrated photonic crystals has recently been proposed as a route to compensate for the reduced optical path in typical lab-on-a-chip sys…
Enhanced circular dichroism via slow-light in dispersive structured media
Jesper Pedersen, Niels Asger Mortensen
Circular dichroism (CD) is in widespread use as a means of determining enantiomeric excess. We show how slow-light phenomena in dispersive structured media allow for a reduction in…
Liquid-infiltrated photonic crystals - enhanced light-matter interactions for lab-on-a-chip applications
Niels Asger Mortensen, Sanshui Xiao, Jesper Pedersen
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 minia…
