Tunneling is for particles.

Electrons can tunnel through sufficiently narrow barriers, thanks to the dual particle/wave nature of matter, but photons either pass through matter without interacting, or they interact and are scattered or absorbed.

The propagation equations of classical electrodynamics are good for situations with large numbers of photons. Calculating probabilities for single photons requires the messy details of quantum mechanics.
