J. Capmany et Ma. Muriel, DOUBLE-CAVITY FIBER STRUCTURES AS ALL-OPTICAL TIMING EXTRACTION CIRCUITS FOR GIGABIT NETWORKS, Fiber and integrated optics, 12(3), 1993, pp. 247-255
In this paper we propose the application of double cavity fiber resona
tors as timing extraction circuits for gigabit networks. Spectral prop
erties of double cavity fiber resonators, including the spectral enhan
cement achieved by means of the vernier effect are outlined. We invest
igate their suitability to obtain low cost all-fiber timing extraction
circuits in broadband optical networks where single cavity structures
previously proposed in the literature cannot be efficiently applied.
