= Fiber optic coupling
{c}
This section is about stuff efficiently getting light into or out of <optical fibers>, or joining two optical fibers together end to end so that light goes through.
Historically this has been an important development, as it is much harder than with wires since <optical fiber> has to be very narrow to work properly, e.g. this is mentioned a lot in <City of Light: The Story of Fiber Optics>.
