The use of coupled photonic crystals cavities for increasing the sensor sensitivity

Abstract

A two-fold way to increase the sensitivity of the optical sensor is proposed and numerically investigated. The sensor based on the coupled photonic crystal cavities is calculated as an illustration of the proposed approach. The correspondence between analytical and numerical modeling approach is demonstrated.

“…This permitted a substantial improvement of the journal indicators calculated in the SCOPUS database (Figures 1-4 [107,34,33,48], in 2010 [108,109,27], in 2011 [54][55] in 2012 [49,110] in 2013 [62,111,112], in 2014 [113-115, 65, 50, 66] and in 2015 [68,39,116,117]) were published by Samara scientists.…”

“…Even The scope of research topics covered by the journal has been extended during 10 years of its publication, now embracing new areas such as plasmonics and diffractive nanophotonics [31][32][33][34][35][36][37][38][39][40][41][42][43], geo-information technologies [44][45][46][47], systems of technical vision [48][49][50][51][52], interpretation and understanding of nanoscale objects images [53][54][55][56], intellectual analysis of video streams [57][58], optical computations [59][60][61], analysis of hyperspectral data [62][63][64], development of hyperspectrometers for Earth remote sensing [65][66][67][68], new types of laser beams with unique properties [69][70][71], sharp focusing [72][73][74], new types of lighting devices [75][76].

“…It was shown that such gratings have a high efficiency and can significantly reduce the size of the projection devices used in mobile phones, etc. Modern computational and technological capabilities allow colleagues and students of I. N. Sissakian to transfer from the tasks of diffractive optics to the problems of diffractive nanophotonics [122][123][124][125][126][127][128][129][130][131].…”

Asymptotic research in computer optics

“…We use this methods not only for the study of diffractive optical elements (in particular, of short-focus DOEs), but also for the study of nanophotonics components [66][67][68][69][70][71][72][73][74], for the design of equipment for hyperspectral remote sensing [75][76][77][78][79] and solving other urgent tasks of diffractive nanophotonics [80]. …”
