Abstract
A compact configuration of a multiport fiber array and a multi-surface optical lens constitutes a low modal noise multimode fiber optical power splitter. In a digital optical system, modal noise manifests itself in modal dependent intensity noise and modal dependent timing jitter. A compact two-part end coupling design improves both properties and is more cost effective, making it a suitable solution for future high bit rate optical system applications.
