We demonstrated the potential application of III-V/polymer nanowires for photonic integrated circuits in a previous paper. Hereby, we report the use of a spot size converter based on 2D reverse nanotaper structure in order to improve the coupling efficiency between the nanowire and optical fiber. A total coupling enhancement of up to a factor 60 has been… (More)
We report the optical characterization of an InP structure constituted by waveguides coupled to microcavity disk resonators. The lateral waveguide confinement is obtained by deep reactive ion etching through the guiding layer. We demonstrate the possibility of tuning optically the resonance wavelength into the illuminating disk resonator. We obtained a… (More)
We present a simple multiplexing structure made of two discrete plasmon wires coupled by two metal nanoclusters. We show that this simple nanosystem can transfer one plasmon wavelength from one wire to the other. Closed-form relations between the transmission coefficients and the nanocluster distances are given to optimize the desired directional plasmon… (More)
We report on the performance of an optical switch based on the use of narrow deep-etched InP waveguides. A DOS-like structure has been designed and fabricated. First characterization results are reported. They show an optical crosstalk value close to -20dB.
The directional transfer of a single photon from one wire to another, leaving all other neighbor states unaffected, is of great importance. We present a simple coupling structure that makes such transfer possible, for any given photon wavelength and linewidth. We give closed-form expressions for the parameters necessary to build such a structure. An… (More)
The aim of this work is to exploit the properties of the GaInAsNSb/GaAs alloy compressive highly strain structure. Ga<sub>1-x</sub>In<sub>x</sub>As<sub>1-y-z</sub>N<sub>y</sub>Sb<sub>z</sub> has been found to be a potentially superior material to GaInAsN for optical fiber communications long wavelength laser (VCSELs) applications. Indeed, this material has… (More)
