Abstract

We report, for the first time to our knowledge, the operation of a cascadable, low-optical-switching-power (∼10 μW) small-area (∼100 μn2) high-speed (80 ps fall time) all-optical inverter. This inverter employs cross-gain modulation, polarization gain anisotropy, and highly nonlinear gain characteristics of an electrically pumped vertical-cavity semiconductor optical amplifier (VCSOA). The measured transfer characteristics of such an optical inverter resemble those of standard electronic metal-oxide semiconductor field-effect transistor-based inverters exhibiting high noise margin and high extinction ratio (∼9.3 dB), making VCSOAs an ideal building block for all-optical logic and memory.
