“…Therefore, it offers an opportunity for further optimization to create the simplest optimal-filled input launch configuration that satisfies the template. Some previous works on the category had been reported by others up to now [13], [15], [16], [18]. We proposed, however, much simpler input launch configuration.…”

We designed and realized multimode polymer optical waveguides on the chips. They were fundamental functional structures and we fabricated them by using simple techniques. We have developed new approach that is simple and nondestructive for multimode polymer optical waveguide evaluations. We examined reliability of the proposed approach by measuring the optical parameters of the realized devices. We have also evaluated the modes distribution affected by inserting additional fibers to the input launch configurations. We realized an optimal-filled input launch by implementing the encircled flux category for 50 core input fiber proposed by the International Electrotechnical Commission . We are successful to achieve insertion loss variation of less than 5% for the waveguides fabricated on top of different substrates.

“…The crossover fiber section was sandwiched between two jaws formed of an elastic material and acts as a point perturbation when an external load is applied. For a point perturbation, lateral displacement in the y-direction induces a distortion of the fiber, which is given by [16]. , E is the area-weighted average Young's moduli of the coated fiber and Ee is for the elastic material.…”

Wideband and Low-Loss Mode Scrambler for Few-Mode Fibers Based on Distributed Multiple Point-Loads

We propose a new type of all-fiber mode scrambler for mode division multiplexed data transmission based on few mode fibers. By randomly placing multiple point-loads along the fiber length, low loss and wideband mode coupling is obtained amongst all the guided modes. The effect of mode coupling is simulated from a single point-load to multiple point-loads with a specific focus on the insertion loss and wavelength dependence. In an exemplar experimental demonstration we present a mode scrambler for step-index two mode fibers incorporating 150 randomly located point-loads. Uniform mode coupling is achieved over the C band with an insertion loss of less than 1 dB.

[17][18][19][20][21] With the modes redistributed, each mode group gradually reaches an equilibrium state. [22][23][24][25][26][27][28] The transmission bandwidth can be improved by transmitting the equilibrium state mode, with good transmission characteristics.…”

The mode dispersion induced in step-index multimode fibers significantly deteriorates the transmission characteristics and bandwidth. To overcome this existing problem, we suppressed the delay of the transmission signal through mode redistribution realized by applying a torsional stress to a fiber using a variable mode controller (VMC). By suppressing the transmission delay, the transmission characteristics and bandwidth of the fiber set in the VMC have been improved. The mode of the fiber set in the VMC achieves an equilibrium mode distribution by mode redistribution. Therefore, the near-and far-field patterns of the VMC were largely stable.
