Abstract
We investigate the mechanisms underlying a mode suppression effect observed in polymer microcavities containing graphene oxide (GO) aiming at the development of on-chip integrable photonic devices. The GO-doped microcavities (cavity loaded Q-factor of 20000 at 1550 nm) are fabricated by means of two-photon polymerization via direct laser writing. The saturable absorption and optically induced thermal lens effects prompted by GO are investigated through nonlinear measurements using both the ultrafast and continuous-wave Z-scan technique and our preliminary results suggest that optically induced thermal lens may be playing a major role in the mode suppression observed in the GO-doped polymer microcavities.
