Abstract :
We investigated a Mach-Zehnder modulator with asymmetric power splitting Y-branches. Output characteristics of a modulator depend on the relation between the power splitting ratios of the front and back Y-branches. By tuning the power splitting ratio of the front Y-branch, we achieved maximum power output operation and high extinction-ratio operation respectively.
