Integrated photonic digital to analog conversion based on unsymmetrical directional coupler

Digital-to-analog converters (DAC) are indispensable functional units in signal transmission and essential component for the optical computing . The photonic DAC that converts electrical digital signals to an optical analog signal advantages in lowering system footprint, power, and cost. Especially with the required bandwidth increasing, it could mitigate the problems faced by its electrical counterparts in dealing with higher sampling rate reach to100GHz. Achieving such a DAC in silicon photonics is promising due to the integration capability of both electronics and photonics and large-scale DAC-based photonic circuits can be further realized for on-chip optical signal processing and computing . This thesis work explores the fundamentals of signal conversion by implementing integrated photonic circuit on silicon on insulator (SOI) platform. The performance of which is investigated through modeling, simulation and measurement.
