摘要：
A photonic integrated signal processor based on the InP-InGaAsP material system consisting of a bypass waveguide and three mutually-coupled micro rings with each ring having two semiconductor optical amplifiers (SOAs) and a current-injection phase modulator (PM) for ultra-wideband signal processing and microwave signal generation is discussed. The signal processor can be reconfigured to perform signal processing functions including temporal differentiation, and temporal integration. The reconfigurability is achieved by controlling the coupling between the rings and the bypass waveguide by a multi-mode interference (MMI) Mach-Zehnder interferometer (MZI) coupler and the injection currents to the SOAs. The current injection PM in a ring is used for wavelength tuning. In addition to signal processing, the signal processor can also be reconfigured to operate as a microwave signal generator. The generation a linearly chirped microwave waveform is discussed.
