Webb10 apr. 2024 · The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth. Such optical filtering is usually sophisticated and beyond the capability of the normal dielectric coating approach. Here we develop a 0.16 nm … Webb18 maj 2024 · The injection-locking signal is the clock transmitted by the clock channel. The injection-locked oscillator behaves as a low-pass filter that filters out unwanted high-frequency jitter beyond the desired jitter transfer bandwidth and duty-cycle errors present in the received clock.
