Paper Abstract

1.278μm laser emission has been observed in a SOI structure which has been nanopatterned to contain an array of nanopores. The optical transition is known to be associated with phononless recombination mediated by the bistable, carbon-related G-center. A physical model is proposed to explain the enhanced optical activity of the G-centers in the presence of the nanopore array. The effects of the SOI, strain, dielectric modification and breaking of phonon k-selection rules on the optical properties of the nanopatterned silicon are addressed. Temperature limitations are discussed.
