FSCEC 광필터에 관한 연구 = A Study on the Optical Filter ofFiber/Slab Composite Evanescent Coupler

다국어 초록 (Multilingual Abstract)

The capacity of telecommunication networks has been increased substantially to meet the request for tremendous rate of information traffic growth due to the demands for multimedia services. As a result, DWDM technologies are emerging to be a prevailing solution of increasing capacity and to enable optical methods of implementing network functions. With the recent movement toward 50-GHz (0.4 nm) channel spacing in DWDM systems, the need for improved components has spawned several new technologies. One such filter technology is the fiber/slab evanescent coupler. The features of the individual isolated waveguides(i.e. the fiber and the slab) play an important role in the performance of the composite structure(e.g. resonance points, FWHM, tunability). For instance, the ACP's approximately determine the resonance points fo the coupler, and the FWHM si inversely proportional to th difference in the dispersion slope of the individual isolated waveguides. For a practical design, study on the features of the DMS will be a good start, because the performance of the coupler is less sensitive to the fiber parameters than to those the external DMS.
