  We propose a scheme for the controllable preparation of a cold indirect
exciton condensate using dipolaritonic setup with an optical pumping.
Dipolaritons are bosonic quasiparticles which arise from the coupling between
cavity photon (C), direct exciton (DX), and indirect exciton (IX) modes, and
appear in a double quantum well embedded in a semiconductor microcavity.
Controlling the detuning between modes of the system, the limiting cases of
exciton-polaritons and indirect excitons can be realized. Our protocol relies
on the initial preparation of an exciton polariton condensate for the far
blue-detuned IX mode, with its subsequent adiabatic transformation to an
indirect exciton condensate by lowering IX energy via applied electric field.
The following allows for generation of a spatially localized cold exciton gas,
on the contrary to currently used methods, where IX cloud appears due to
diffusion of carriers from spatially separated electron- and hole-rich areas.
