RARE-EARTH-DOPED LITHIUM NIOBATE WAVEGUIDE STRUCTURES

摘要

in a waveguide structure having a rare earth doping distribution in a light guide channel (lk) arranged in a crystal surface (s) of lithium niobate, doping rare earths are approximately coaxial with the light guide channel (lk) in an active zone, t land limited ().the light guide channel (lk) is directly released from the crystal surface (s) and a lateral extension (w) is limited.
