The reference Open Source Voxel Engine is Minetest: https://github.com/minetest/minetest

The library used in Minecraft (not sure if call it a engine): https://www.lwjgl.org/ https://www.lwjgl.org/frameworks using it.

In this ticket we can also explore how to use Unity for creating a Minecraft like game, using Unity as a Voxel engine. There are several tutorials showing how to do it.

And the same for Unreal Engine 4.

Both of them are not Open Source, but the experience will be interesting.
