Abstract
A photonic N-to-one single-mode combiner is disclosed. In embodiments, the combiner receives multiple single-mode photonic inputs (e.g., via single-mode optical fibers) and combines the single-mode inputs into a multi-mode photonic output via photonic lantern. The multi-mode photonic output is converted via high-power, high-speed photodiode into an RF/electrical output which in turn drives an electro-optical modulator, modulating a second optical beam (e.g., a laser generated by a laser emitter of the combiner) to generate a single-mode photonic output signal.
