Jamming wouldn't break line-of-sight or optical communication. Imagine drones that can simply see one another, and communicate by changing color (e.g. with LEDs).
Lasers are already used for inter-satellite communications, so there's no need to just use gross color shifting (though perhaps the BOM impact would be less).
Related side story: my resume had something about PKI in it so I kept getting calls from Boeing recruiters trying to fit me into a job doing said satellite laser comms (presumably using PKI). I kept telling them I knew nothing optics-related aside from basic Newtonian stuff, and they kept calling me back. I hope they finally found someone.
