Abstract :
Six-element quarter-wave-shifted DFB arrays have been fabricated using holographic printing with e-beam generated quartz phase masks. A standard deviation of s=0.18 nm from a uniform WDM channel spacing has been achieved, a dramatic improvement over the values associated with wafer-wide DFB wavelength distributions
