Theory and modeling: electrical and optical waveguide process in corn-shaped optical head laser on near field optical disc

摘要

The paper introduces characters of NFOD. It presents electrical and optical wave- guide process problems in corn-shaped optical head of NFOD and gives approximate calculations in first-grade approximativity of corn-shaped optical head of NFOD. The result is an important basis for the NFOD optical head design with ultra thin active layer and ultra small spot laser.
