Injection locked on-chip laser to external on-chip resonator

A system, comprising:

• a first integrated circuit chip, comprising:
• a first laser;
• and
• a second laser;
• and
• a second integrated circuit chip, the second integrated circuit chip and the first integrated circuit chip being separate integrated circuit chips, the second integrated circuit chip comprising:
• a resonator formed of an electrooptic material, the resonator configured to:
• receive light emitted by the first laser of the first integrated circuit chip and return feedback light to the first laser of the first integrated circuit chip, wherein the feedback light returned by the resonator causes injection locking of the first laser to the resonator to control the light emitted by the first laser;
• and
• receive light emitted by the second laser of the first integrated circuit chip and return feedback light to the second laser of the first integrated circuit chip, wherein the feedback light returned by the resonator causes injection locking of the second laser to the resonator to control the light emitted by the second laser.

A method of injection locking a laser to a resonator, comprising:

• emitting light from the laser on a first integrated circuit chip to the resonator on a second integrated circuit chip, the first integrated circuit chip and the second integrated circuit chip being separate integrated circuit chips, the first integrated circuit chip being optically coupled with the second integrated circuit chip,
• wherein the resonator is configured to receive light emitted by the laser and return feedback light to the laser, and wherein the feedback light returned to the laser causes injection locking of the laser to the resonator to control the light emitted by the laser;
• receiving feedback light from the resonator at the laser, the feedback light causes injection locking of the laser to the resonator;
• and
• transmitting injection locked light outputted by the laser from the first integrated circuit chip into an environment.
