30 December 2004 Multichannel integrated optical filters for spectral signature recognition
Author Affiliations +
Recent advances in the development of two-dimensional holographic Bragg reflectors in planar lightwave circuits have demonstrated the feasibility of highly customizable multi-wavelength filters based on photonics nanostructures programmable to recognize spectra with up to 2000 spectral lines. Such filters rival or exceed performance of free space gratings, thin film filters and Bragg gratings and may be monolithically integrated with detectors in III-V active materials or as passive devices in silica. This new technological platform holds a great promise of being next-generation optical engine for spectral signature recognition in the field of remote sensing, biological, chemical and defense applications.
