Abstract

The waveguide dichroic coupler in lithium niobate is used to couple 1.55 micrometers signal and 0.98 micrometers pumping source into Er-doped fiber simultaneously. In order to improve the function of an Er-doped fiber amplifier, a Ti/Mg double diffusion method is employed to increase the coupling efficiency for the dichroic coupler to the Er-doped fiber in the endface configuration. The configuration of dichroic coupler has a buried guiding core and high coupling coefficient. Those desired functions can be achieved by optimizing the design of the relative fabrication parameters.
