Etude des propriétés remarquables de nanofils optiques InP/polymère en vue de la réalisation de fonctions optoélectroniques hyperfréquences

Abstract : This work gives an insight into the possible application of high index contrast based nanophotonics to process microwave - photonic functions such as a tunable time delay and an all-optical ultrafast switching. InP embedded in a low optical index matrix (benzocyclobutene) by wafer bonding is considered for this purpose to take benefit of III-V material electro-optical properties. High resolution technological process is required due to the high sensitivity of the nanowires to any change in their size. The optical characterisation proved the quality of the process, through the highlighting of state-of-the-art propagation loss (less than 10 dB/cm) and strong decrease of coupling loss. Such good propagation characteristics allow us to use the InP/BCB nanowires as a first step for active functions and to study physical phenomena they are based on. So, Bragg gratings on InP/BCB nanowires were processed and characterized successfully. Slow light phenomenon at the band edge of such structures should allow 1 ns microwave delay for a 1mm long grating. In addition, absorption-saturation was demonstrated opening the way to an all-optical switch. Furthermore, propositions are made towards ultrafast and low power devices.
