Abstract
Properties of one-dimensional photonic crystal heterostructures having a photonic band gap in the near infra-red spectrum are examined and photonic crystals with n-i-p-i superlattices are designed for information technologies. For the first time, the availability of n-i-p-i crystals in photonic band gap heterostructures is considered and different configurations of microcavities are described. Optical properties and output characteristics of the photonic crystals in the GaAs-AlGaAs and GaAs-GaInP systems are determined and possible applications for optical switchers, filters, single-mode laser sources, and amplifiers are discussed.
