1.5 μm band efficient broadband wavelength conversion by difference frequency generation in a periodically domain‐inverted LiNbO3 channel waveguide
CQ Xu, H Okayama, M Kawahara - Applied Physics Letters, 1993 - pubs.aip.org
Efficient 1.5, um band wavelength conversion by difference frequency generation (DFG) in a
periodically domain-inverted LiNbOs channel waveguide is demonstrated, and DFG
e5ciency as high as 40% W-'cmw2 is obtained. Nearly constant wavelength conversion
efficiency has been confirmed over a broad wavelength range of 30 nm, which is the largest
value ever reported. A 1.5 pm band wavelength converter is considered to be a key device
in future wavelength division multiplexing (WDM) optical communication systems. For …
