Abstract
We describe the fabrication and performance of lambda/4 shifted DFB la ser arrays made using electron beam-generated near field holographic g rating masks. Precision requirements for these masks are discussed. We also examine the physical phenomena that contribute to wavelength var iations in DFB lasers. Projections are made regarding the epitaxial th ickness, composition, and waveguide etching control required to achiev e a source wavelength absolute reproducibility of +/- 0.1 nm.
