Amplification in photonic crystal heterostructures with active media from doping superlattice layers

Abstract

Computer simulation demonstrates that asymmetric photonic crystal heterostructures with defect layers provides lasing at two different wavelengths and in opposite output directions. The light field distribution and radiation transport in the photonic structures are strongly affected by the n-i-p-i layers periodicity, dispersion characteristics of the components, and. conditions at the interfaces. Described photonic crystal. heterostructures can be attractive for a wide variety of applications. In particular, they can be used as single-mode laser sources or amplifiers at the near-infrared spectral region.
