Abstract

In this work we analyze numerically and experimentally new active waveguides based on a bilayer structure composed by a passive polymer and an active poly(mehtyl methacrylate) (PMMA) film doped with CdSe colloidal quantum dots (QDs), namely a nancomposite. In a first bilayer structure a planar PMMA layer is deposited on top of the nanocomposite, where the signal beam intensity is enhanced because this cladding layer is able to collect radiated emission of QDs. Moreover, the pump beam is also propagating through the cladding without limitation by QD absorption. These results are extended to a second bilayer structure, where ridge patterns of a commercially available resist (SU-8) are deposited on the top of the nanocomposite active layer. These SU-8 patterns are also able to guide with low absorption losses both pump and signal beams. The optimum geometrical parameters of the bilayer structures were properly designed to optimize the light waveguiding, previous to their fabrication and optical characterization. For this purpose, a spontaneous emission model has been developed and programmed into an active beam propagation method. This technology can be the base for developing integrated photonics on silicon at visible and telecom wavelengths.
