Abstract :
Optical interference filters with continuously modulated refractive indices throughout their thickness (rugates) are designed and fabricated using microwave plasma-assisted chemical vapour deposition techniques. Intelligent modelling and control techniques are used to model the process and improve the reproducibility of reflection filters
