Abstract

Near the band edge of a one-dimensional photonic band gap structure
the photon group velocityapproaches zero. This effect implies an
exceedingly long optical path length in the structure.If an active
medium is present, the optical path length increase near the photonic
band edge canlead to a better than fourfold enhancement of gain.
This new effect has important applicationsto vertical-cavity surface-emitting
lasers.
