Pixelated-core Large Pitch Optical Fibre Design

This paper is reporting design and simulation of a pixelated-core large pitch optical fibre. With this new design, existence of higher order modes, mode instability at high power levels, mode shrinking and gain reduction upon bending has been solved and the bending loss is negligible in the frequently used bending radius of 3 cm to 5 cm. Even down to 3 mm bending radius, magnitude of bending loss can also be suppressed by three orders.
