Abstract
To enhance the channel impulse response and signal quality through a multimode fiber, the incident wavefront into a multimode fiber may be controlled using phase masks, gratings and spatial light modulators. In this paper, an elegant technique for controlled coupling into a multimode fiber is demonstrated using a solid-core photonic crystal fiber to reduce differential mode delay in a multimode fiber. The increase in the number of tiers of a solid-core photonic crystal fiber is shown to reduce differential mode delay and improve the bit-error rate of a multimode fiber channel.
