1. A switchable light transmission module, comprising:
a substrate having a first surface defining at least part of an enclosed volume;
a porous layer disposed on the first surface and in fluid communication with the enclosed volume; and
a reservoir in fluid communication with the enclosed volume and including a non-dissolving fluid;
the reservoir being configured to supply the fluid to the enclosed volume such that the fluid contacts the porous layer, wherein the porous layer is wetted when the fluid is in the enclosed volume, and is dried when the fluid is in the reservoir,
wherein the fluid has a refractive index that is within about 30% of the refractive index of the porous layer.
