abstract = "Optical communications currently demands for lossless signal splitting along passive optical networks. This can be achieved by deploying low-cost sol-gel integrated circuits based on silica-on-silicon technology. Compact splitters are accordingly fabricated exhibiting low loss, low PDL and good uniformity; the splitters are integrated with active fibers and amplifying splitters are demonstrated.",

note = "Funding Information: At NP Photonics the splitters are being made for the development of amplifying splitters. By amplifying splitters we mean lossless splitting, i.e. to image the input power at each output port. Say, if there is 1 µW of power at the input we intend to collect 1 µW at each output through amplification. Therefore, for 1×16 splitter we need approximately 16 dB gain at the input to achieve such a functionality. NP erbium doped fiber can provide sufficient gain at the input to achieve this over entire C band. Figure 3 shows the demonstration of 1×16 passive and amplifying splitters. The figure illustrates the response of one of the splitter outputs to various 1550-nm signals: 50 µW, 100 µW and 200 µW. Under passive operation the output varies from about 1 to 4 µW for different signals. While under active operation the output power is just about the input power. This is achieved by adjusting the active fiber gain via varying the 980 laser diode current.
