We describe sub-100 nm wire fabrication in GaAs/AlGaAs multiquantum wells (MQW) by focused ion beam lithography and the time-resolved absorption measurements of the narrow wires. It is shown that the strong optical nonlinearity of excitons is preserved, even in wires of 130 nm width, and having a fast recovery time of 11 ps. The authors have found a strong reduction of the recovery time with decreasing wire width.
