Abstract
We investigate the performance of a highly compact ( $\leq 1$ cm) all-fiber multimode interference (MMI) device for splitting optical power from a standard single mode fiber (SMF) input port to four (4) SMF output ports. In C-band, the best and worst case uniformity among the output ports are obtained as 0.14 dB and 1 dB, respectively. This compact device provides a low-cost, high-performing solution for potential usage in optical networks.
