Abstract

This paper reports on the development of a new laser-based chemical sensor. The optical sensor is based on the modification of the resonant cavity of a distributed-Bragg-reflector (DBR) laser. Part of the cavity (phase section and/or DBR grating) is covered by a sensitive layer that changes its refractive index as a result of interaction with a given chemical. This produces the change of optical cavity length, resulting in the lasing frequency shift. The results of modeling and preliminary experiments proving the concept of chemical sensing are presented.
