<p>Wavelength filtering in the optical spectrums is accomplished by a fiber optics device mechanically separated from the device carrying the broad spectrum of wavelengths. The filter elements may be linear or loop shaped, and preferably utilize lateral coupling between fiber elements. Individual filter elements may be ganged for increased selectivity. The filters of the present invention have typical line widths of .01A.degree. to 1A.degree. in the .2 to 3 micron region.</p> |
