We consider in-plane electrostatic traps for indirect excitons in coupledquantum wells, where the traps are formed by a laterally modulated gatevoltage. An intrinsic obstacle for exciton confinement in electrostatic trapsis an in-plane electric field that can lead to exciton dissociation. We proposea design to suppress the in-plane electric field and, at the same time, toeffectively confine excitons in the electrostatic traps. We presentcalculations for various classes of electrostatic traps and experimental proofof principle for trapping of indirect excitons in electrostatic traps.Comment: 4 pages, 3 figure
