Variable Slope, Multi-Octave Radio Frequency Filters	Customizable: The combined signal may be applied to a standard low-pass, band pass, or high-pass optical filter. The filter can be implemented with any number of poles for a maximum defined-slope, and the choice of pass type may be made according to the desired slope direction. Variable: By moving the optical carrier up and down in frequency through the transition band, the slope of the RF signal can be continuously varied. Versatile: The technology can be used as is or it can augment existing RF lab equipment.	7680
