Summary, Etc.  

요약Optical signal processing can play an important role in numerous optical systems broadly used in today's world, such as optical interconnects and networking, optical computing and machine learning, RF over fiber, lidar, etc. While these systems contain and transmit the data in the optical format, the information processing occurs primarily using CMOS circuits in the electrical domain, which necessitates power-hungry and latency-inducing opto-electric-opto conversion. Performing appropriate signal processing on the optically modulated information signal may reduce the power consumption and latency across the system while bolstering security and high-speed data rate. Silicon photonics integrated silicon (Si PIC), along with the advances in materials and devices, are the key enabling technologies growing the optical signal processing practical utilization.This thesis features different integrated optical signal processing circuits and systems in both the analog and digital domains. True time delay lines are key enablers in analog optical signal processing; therefore, a low-loss variable delay line, leveraging wide straight waveguides and compact bends, is implemented. Targeting optical signal processing occurs at remote nodes with hard access to reliable electrical supply and control signals. An all-optical remotely controlled and biased signal processing system, utilizing WDM laser-delivered bias and control signals, is proposed. Two examples are employed to demonstrate this system: an amplitude modulator and a two-tap sequence detector. Universal optical input - optical output cascadable logic gates are also reported, facilitating digital optical signal processing. These proposed optical processing systems and circuits are fabricated in a commercial silicon photonics process and experimentally demonstrated.
