Abstract
A pitch averaging Bragg grating includes a plurality of grating peaks spaced by different pitch values. By selecting the different pitch values to have an average pitch value equal to a target pitch value, the pitch averaging Bragg grating can be made to perform like a constant pitch Bragg grating having a fixed pitch at the target pitch value. The different pitch values can be multiples of the minimum placement resolution of a production tool to be used to produce the Bragg grating. The pitch averaging Bragg grating can be used in place of constant pitch Bragg gratings in optical devices and systems, such as DFB lasers, DBR lasers, optical spectral filters, multi-wavelength laser arrays, and WDM systems.
