Fabrication and Characteristics of Plastic Optical Fiber Directional Couplers

Fused Fiber Couplers: Basic Theory and Automated Fabrication

Optical fiber couplers for precision spaceborne metrology.

We describe the optical and mechanical design, construction philosophy, and testing of a pair of matched, spaceflight-qualified fiber couplers. The couplers were developed for the LISA Pathfinder mission but are relevant for other applications-both on ground and in space-where a robust fiber coupler with well-controlled beam parameters and stable beam pointing is required. This particular imple...

Switching dynamics of solitons in fiber directional couplers.

A simple analytical approach based on a variational formalism is applied to an analysis of the switching dynamics of solitons in fiber nonlinear directional couplers. It is demonstrated that soliton switching may be described by a simplified Hamiltonian model that displays three different regimes of soliton dynamics, depending on the universal parameter, which is the ratio of the squared intens...

Optical bandwidth and fabrication tolerances of multimode interference couplers

Analytical expressions are derived which relate the optical bandwidth and the fabrication tolerances of multimode interference (MMI) couplers to their most important design parameters. These expressions compare adequately with mode analysis simulations. For strong guided structures, the optical bandwidth is shown to be inversely proportional to the number of input and output ports N and to the ...
