Ayerden, N.P. (author), Ghaderi, M. (author), De Graaf, G. (author), Wolffenbuttel, R.F. (author)The design, fabrication and characterization of a highly integrated optical gas sensor is presented.

Using the tapered resonator cavity of a linear variable optical filter as a gas cell enables ultimate miniaturization,...conference paper 2015
