掺铒波导放大器的高性能化最新进展OA

The explosive growth in bandwidth demand driven by data centers,the 5th/6th Generation Network(5G/6G)commu-nications,and high-performance computing has made photonic integrated circuits crucial for high-density,low-loss information processing.As key devices for compensating signal loss in photonic chips,Erbium-Doped Waveguide Amplifier(EDWA)s have demonstrated significant application potential in optical communications,sensing,and optoelectronic systems due to its miniatur-ization,low power consumption,and high integration capability.This review systematically summarizes recent advances in rare-earth-ion-doped integrated amplifiers.It provides an in-depth analysis of key factors affecting core performance metrics of ED-WA,and compares the performance advantages and limitations of different Wavelength Division Multiplexing(WDM)schemes.Finally,we outline future development directions for high-performance EDWA,highlighting their potential in dynamic gain con-trol,heterogeneous integration,and broadband operation,thereby offering technical insights to facilitate the transition of EDWA from laboratory research to large-scale communication applications.
