Gerken and D. A. B. Miller, "Thin-Film (DE)MUX based on Step-Like
Spatial Beam Shifting," IEEE Lasers and Electro-Optics Society
2002 Annual Meeting, Glasgow, Scotland (November 10-14, 2002). Paper
Using spatial beam shifting
a single dielectric stack can demultiplex multiple WDM channels. We
demonstrate in theory and experiment that a compact, cost-effective (DE)MUX
with flat-top passbands and low loss can be achieved.
