✦ Synopsis
In this paper, we present a study of the crosstalk level of an acousto-optic tunable filter (AOTF) operating with ultrashort light pulses (2 ps). Initially, we consider the performance of the device, with several lengths, operating in the linear and nonlinear regime without loss. Given low pump power (P 0 ϭ 1 W), the crosstalk level (XL) of this device always increases with the length of the AOTF, for three different device configurations: the soliton regime, the dispersionless regime, and the linear regime. For shorter devices (L/10 Ͻ L Ͻ L), the soliton regime presents the lower XL. However, this behavior is reversed for longer devices, where the filter bandwidth is much shorter than the pulse bandwidth. For the dispersionless regime and low pump multiwavelength router.
