متن کاملLow loss fiber to chip connection system for telecommunication devices
We present a method for low loss coupling of multiple fibers to optical waveguides. Simultaneous alignment of multiple fibers is done by placing the fibers in a V-groove array. Coupling efficiency can be enhanced by placing a high numerical aperture (HNA) fiber (MFD 4 μm) between the standard telecom fiber and a horizontal tapered waveguide. The splicing loss between the standard telecom fiber ...
متن کاملOptical 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...
متن کاملDesign of a Photonic Bandgap Fiber with Optimized Parameters to Achieve Ultra-Low Confinement Loss
In this paper, a novel design of all-solid photonic bandgap fiber with ultra-low confinement loss is proposed. The confinement loss is reduced remarkably by managing the number of rods rings, up-doping level, pitch value, and rods diameters. Moreover, the designed PCF shows ultra-flattened dispersion in L- and U-band. Furthermore, a new design, based on introducing of an extra ring of air h...
متن کاملOptical 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 ...
