Simultaneous compensation of dispersion and losses using Er-doped double-core optical fiber
2004
The Er-doped double-core dispersion compensating fiber (EDDCF) has been fabricated using modified chemical vapor deposition (MCVD) technique. We have obtained 14 dB gain at 1550 nm (using a diode laser of 980 nm wavelength which provides 100 mW of pump power) with dispersion of about −165 ps/km nm. It is useful for the optical fiber network where amplification as well as negative dispersion is necessary. We are the first to report the experimental realization and characterization of the EDDCF.
