    Abstract

    Ytterbium (Yb3+)-doped potassium double tungstate (KYW) is a promising material for optical amplification due to its high and broad gain characteristics around 1 μm wavelength. The KYW channel waveguide amplifier coupled to fiber ends with mode field diameter of 6 μm is optimized. Numerical results show that for 53.5 at. % Yb3+ doping over 50 dB fiber-to-fiber gain is attainable in single mode channel waveguide designs with layer thickness and channel width less than 7 μm and 11 μm respectively. The optimum device length being as short as 1 mm is highly promising for short- distance optical interconnects with stringent device footprint requirement.
