title: Coupling mechanisms and transfer functions of optical fiber devices.
abstract: Modal-power transfer functions for two basic coupling mechanisms, i.e., scattering coupling and overlap coupling, are derived. Optical fiber devices such as fibers or cables, connectors, splices, and power splitters can be characterized by modal-power transfer relations based on these transfer functions. Experimental results show that the transfer functions are independent of launch conditions.
