Abstract
A distributed wavelength optical narrow band interference filter integratable with silicon that give high, homogeneous transmission over the visible spectrum is designed as proposed by Dr. Holm-Kennedy. Filter designs are simulated in this report starting from the most fundamental design to an acceptable design step by step as proposed by Dr. Holm-Kennedy. The final design uses seven thin film layers altogether. For a maximum transmittance of about 50%, the wavelength bandwidth is 20 nm. For a maximum transmittance of about 70%, the bandwidth is 38nm. This design is versatile in that it can be used as it is at 50% maximum transmittance with excellent rejection. Or the disign can be significantly improved by adding additional layers.
