Our tests focuses on the performance of integrated opti-\r\ncal test structures using femtosecond pulses in the 1550nm spectral range. A primary objective\r\nis to understand the behaviour of silicon photonic waveguides that can be further employed in the\r\nimplementation of an optoelectronic phase-locked loop (OEPLL) in silicon photonics technology.\r\nA comparison of our results, as well as a discussion on the di®erent optoelectronic phase noise\r\nmeasurement techniques are presented. Our ¯ndings provide insights that can be leveraged to\r\noptimize the design and performance of ultra-low phase noise on-chip OEPLL systems locking\r\nto mode-locked laser (MLL) signals. In the future such systems can be essential for advanced\r\ncommunication and sensing applications.","lang":"eng"}]}]
