Abstract:
We fabricate a hybrid integrated self-injection locked (SIL) laser, achieving a 42 Hz linewidth via a high-quality Si3N4 microring resonator, and utilize it to construct a net 400 Gb/s self-homodyne coherent transmission system, tolerating 1 km of fiber length mismatch without performing carrier phase recovery.
