• 論文の詳細を見る

• For precise chirp parameter control, we investigated x-cut LiNbO3 single-drive asymmetric Mach-Zehnder modulators with extinction-ratio adjustable active Y-branch structures, which can enhance on-off extinction ratio. The chirp parameter of the modulated output was precisely measured by using high extinction ratio operation. Experimental results show that it is possible to fabricate modulators with desired chirp parameters.
