Abstract:
Coupling power propagation on MXN monolithic fiber coupler has been calculated by using
matrix transfer based on coupled-mode theory. Launching input power to one fiber on linear 1X7
monolithic fiber coupler shows that power is distributed to the other fibers with different coupling
velocity. It is found that the outer fiber has the slowest coupling velocity and high transferred
power. The measurement of output power of 1X7 fiber coupler as fiber combiner has been
theoretically and experimentally done. The experimental result is compared to the theoretical
model. A small different peak at certain distance occurs due to the coupling velocity. This MXN
multi fiber coupler is applied for various optical power circuits
