The ability to create and characterise an array of coupled nanowires is an important step towards understanding the physics of systems like stripe phase superconductors, sliding Luttinger liquids, anisotropic materials made up of quasi-1D chains, etc. Here, we create nanowire arrays using Ultra Low voltage Electron beam lithography. ULVEBL has been shown to create conducting nanostructures in the 2D electron system at the LAO/STO interface. We study the transport properties of this system at low temperatures and high magnetic fields. We show that it is possible to reversibly tune the interwire coupling using a back gate voltage and magnetic field. This can act as a tool to study the dimensionality cross over from 1D to 2D. This can potentially be extended further to create more complicated structures using ULV-EBL that can model the behaviour of other materials and lattice models.
