Higher-order defect mode laser in an optically thick photonic crystal slab

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Jingqing Huang, Axel Scherer, , | Summary: The use of an optically thick slab may provide versatile solutions for the realization of a current injection type laser using photonic crystals. Here, we show that a transversely higher-order defect mode can be designed to be confined […]

Large-field-of-view Chip-scale Talbot-grid-based Fluorescence Microscopy

Kavli Affiliate: Paul W. Sternberg | First 5 Authors: Shuo Pang, Chao Han, Mihoko Kato, Paul W. Sternberg, Changhuei Yang | Summary: The fluorescence microscope is one of the most important tools in modern clinical diagnosis and biological science. However, its expense, size and limited field-of-view (FOV) are becoming bottlenecks in key applications such as […]

High-Q impurity photon states bounded by a photonic-band-pseudogap in an optically-thick photonic-crystal slab

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Andrew Homyk, Sameer Walavalkar, Axel Scherer, | Summary: 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. We find that the density of in-plane Bloch […]

Irregular transcription dynamics for rapid production of high-fidelity transcripts

Kavli Affiliate: Martin Depken | First 5 Authors: Martin Depken, Juan M. R. Parrondo, Stephan W. Gril, , | Summary: Both genomic stability and sustenance of day-to-day life rely on efficient and accurate readout of the genetic code. Single-molecule experiments show that transcription and replication are highly stochastic and irregular processes, with the polymerases frequently […]

Measuring the spatial extent of individual localized photonic states

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Marko Spasenovic, Daryl M. Beggs, Philippe Lalanne, Thomas F. Krauss, L. | Summary: We measure the spatial extent of individual localized photonic states in a slow-light photonic crystal waveguide. The size of the states is measured by perturbing each state individually through a local electromagnetic interaction with […]
