title: Nonlinear restrictions of Talbot-like spatial filters in semiconductor laser arrays.
abstract: We consider the operation of an active Talbot spatial filter in semiconductor laser arrays. High linearity of filtering can be achieved in lasers with separate driving systems for the array and filter regions by the use of a constant driving current in the filter region. If the regions are pumped equally, then lasers with high threshold current will show nonlinear light-current characteristics.
