Abstract
A fiber Bragg grating DFB-DBR interactive laser is provided by an optical fiber section which is doped with at least one gain-inducing material. At each end of the section there is a fiber Bragg grating which operates as part of a fiber DBR laser. Between these two gratings there is a third fiber Bragg grating which has a 90.degree. phase shift region. The third fiber Bragg grating effectively operates as part of a fiber DFB laser. Each of the fiber Bragg gratings has a narrow reflective linewidth centered about the same wavelength so that the optical fiber section operates as a fiber Bragg grating DFB-DBR interactive laser upon sufficient pumping energy. The resulting fiber Bragg grating DFB-DBR interactive laser can be appropriately connected to pumping laser sources and WDM couplers to create fiber laser sources which are particularly adaptable to fiberoptic networks, particularly WDM and DWDM networks.
