Optical fibers consisted of multiple cores (multi-core fibers, MCFs) are widely regarded as the leading solution path to the optical communications capacity crunch. MCFs are also used in high power lasers, microwave photonics, and shape-sensing applications. The most common paradigm for the design and employment of MCFs is to try and restrict the direct coupling of power among different cores through...
Opto-electronic oscillators (OEOs) are sources of radio-frequency (RF) tones with low phase noise [1], which serve in radars, coherent communication and precision metrology. OEOs consist of hybrid cavities: light is modulated by an RF waveform and propagates over a length of fiber. Light at the fiber output power is detected, and the recovered signal is then fed back to modulate the optical source...
