Abstract
In this paper we present a novel sensor based on the modification of a distributed Bragg reflector (DBR) laser: the optical path length of a resonant cavity is changed thus changing the resonant frequency. The external cavity of the DBR laser, with a sensitive element within is u sed to detect chemical species and temperature. We will show the expec ted resolution as well as preliminary experimental results. (C) 1998 P ublished by Elsevier Science B.V. All rights reserved.
