A wavalength selectable wdm source using a fiber sagnac loop filter

Ergül, Özgür
The demand for faster data transmission has been increasing since the wide acceptance of the Internet. To meet this ever increasing demand, optical communication systems use Wavelength Division Multiplexing (WDM) to transport more information per fiber by utilizing multiple wavelength channels. Multi-wavelength laser sources are one of the most important components of such WDM systems. In this thesis a multi-wavelength laser source is proposed. A fiber Sagnac loop filter is used to produce a grid pattern with peaks at a certain set of wavelengths. Then any desired channel is chosen from the grid by using an adjustable Fiber Bragg Grating.
