Optical would be simpler.
How? Assuming that the camera is underwater and the lights are not, and the camera is in an underwater housing, how is optical a better solution for triggering the lights?
There are lots of ways to solve the problem, but we really don't know what the problem is exactly. This is a a classic case of someone asking a technical question of a forum, without any clue what they are actually trying to do. For example why do you automatically assume that the lights are above water and the camera under?
I did underwater photography for many years (my first serious camera purchase in 1969 was a Nikonos II and I later used a Nikonos V with u/w flash) so my assumption was the OP was asking about a situation where both camera and slave flash were underwater in waterproof enclosures.
Most u/w camera enclosures, while equipped with waterproof connectors for an attached flash, are not designed to accommodate a PW sticking up in the hot shoe. So with multiple flash the u/w a flash attached to the housing usually triggers optical sensors on any slave flashes used.
In the case of where flashes are above water and the camera under optical could work with the simple expedient of putting a sensor like a Wein peanut on the end of a long PC cord attached to one of the flashes (or a PW transmitter) and dangling it in the water where is can see the trigger flash from a u/w flash attached to the housing. Silicone or epoxy could be used to make the Peanut / cord connection waterproof.
Another alternative in swimming pool type of scenario where the camera was in a standard u/w housing would be to keep the PW transmitter above water with the lights, connected to the housing with a long PC-cord. Granted its not a completely wireless solution, but with the simple expedient of putting a float on the cord it would hang vertically out of the way.
