laser for connecting CPU to DRAM?

Very long time ago there was this idea about replacing all those wires (from CPU to DRAM) with some fiber optic.
Someone knows if that is still a research subject, putting some laser LEDs on the main CPU and DRAM chip, maybe different (a lot of) laser frequencies to achieve bandwidth?
Or maybe just for PCIe?
Or is it now another dead idea?
