title: Transmission loss caused by an angular misalignment between two multimode fibers with arbitrary profile exponents.
abstract: The coupling efficiency between two multimode fibers with an angular misalignment is calculated. For the practically interesting cases of parabolic and step-index profiles, closed-form expressions and simple approximations are derived. Furthermore a general loss formula for small tilt angles and arbitrary profile exponents is presented.
