摘要：

The applicability of rod-type photonic crystal waveguides to enhance the absorption sensitivity of methane gas has been investigated. It has been shown numerically that a suitably optimized rod-type photonic crystal waveguide has potential to form the miniaturized absorption spectrometer. The key advantage of this sensing architecture is the enhancement of the absorption sensitivity of the methane gas due to the slow-light effect. (C) 2015 Elsevier GmbH. All rights reserved.
