Abstract:
An on-chip spectroscopic sensor includes a tunable diode laser. A laser driver for drives the tunable diode laser. An analyte test cavity receives a chemical sample and exposes the received chemical sample to light from the tunable diode laser. An optical detector detects light emerging from the analyte test cavity as a result of the laser exposure. A spectral analyzer determines a spectrum of the emerging light, matches and removes one or more known optical fringe patterns from the determined spectrum, and determines a composition or concentration of the chemical sample from the optical fringe pattern-removed spectrum.

Claim (Index 18):
The method of  claim 13 , wherein the background removal model is constructed using the formula:\n I t ( v ( t ))= I 0 ( v ( t ))\u00d7 e \u2212\u03c3(v(t))NL \u00d7fringe background where v(t) represents laser frequency as a function of time, I t  represents transmitted laser intensity or equivalently the measured spectrum, I 0  represents incident laser intensity, \u03c3 represents cross section of light absorption by a single particle, L represents optical pathlength of the sensor, and N represents analyte concentration.
