Toward an integrated silicon-photonic module for widely tunable narrow-line RF source using injection-locking

Through the use of a narrow-linewidth low-frequency oscillator, optical modulator, and injection locking, we have developed a system for generating widely tunable, narrow-line RF signals from a pair of injection-locked lasers. Here we focus on the design and implementation of an integrated device including photonic sources and modulators to realize the system described above. Specifically, we report on the creation and mixing of two tunable lasers on a silicon platform with a heterogeneously integrated gain medium realized in a III-V material system.
