Infinite Square Well for Bosons in an optical lattice

[TheForce]

I'm working on a research project and was wondering what you could use to experimentally create a periodic infinite square well (dirac comb?) in a direction orthogonal to a different potential, say a periodic potential.
To help you understand what I'm trying to do picture a grid of atoms and take there to be a periodic potential in one direction and an infinite square well periodic potential in another.

The idea is to restrict the movement of a particle in one direction. The theory is simple, but I don't know very much about practically implementing it.

Any ideas? Comments? Concerns? Any feedback appreciated!

N.B. the periodic potential is an optical lattice, I don't think I can use an MOT to approximate my square well because I need the thing to be on a scale of nms and be periodic.

One way to create an experimentally periodic infinite square well in a direction orthogonal to a different potential is to use laser tweezers. This technique involves trapping a particle in a standing wave of light, which can be used to create a periodic potential in the direction of the laser beam. By adjusting the laser intensity and wavelength, you can create an infinite square well in the direction perpendicular to the laser beam. You can also adjust the frequency of the laser beam to create a periodic potential.
