Researchers have developed a high-gain optical parametric amplifier (OPA) on a thin-film lithium niobate (TFLN) chip, achieving significant signal amplification for optical communication applications using a continuous-wave pump.
This research demonstrates the first ultra-broadband, high-gain, continuous-wave optical parametric amplifier on a compact photonic chip, surpassing the performance of traditional fiber-based systems and paving the way for next-generation optical communication networks.
