Light-amplification-assisted sum-frequency generation in erbium-doped thin-film lithium niobate optical waveguides
{{output}}
Erbium-doped thin-film lithium niobate (Er3+:TFLN) enables integrated photonic devices through its efficient photoluminescence. However, the fixed transition energies of erbium ions intrinsically restrict emission to the telecommunications C-band (1530-1565 nm... ...
