摘要： A method for fabricating an optical fiber coupler device includes a step of tangibly fusing a first outer cladding of a first optical fiber with a second outer cladding of a second optical fiber as a result of pulling and heating the first and second optical fibers at lengths not exceeding 3 mm to form a first region of structurally-integrated with one another first and second optical fibers, and a step of heating a second, neighboring region of these fibers to configure the device to transmit optical power of at least about a hundred Watts and up to at least a kWatt from the input end to the output end with a value of throughput loss not exceeding 0.2 dB.
