Role of Bend on the Optimization of 980-nm-Pumped Erbium-Doped Fiber Amplifier
(1995)
We describe optimization performed numerically for a 980-nm-pumped erbium-doped fiber amplifier in the presence of bending, for both fully and fractionally doped cores.All calculations are carried out using three-level ...
Equivalent Waveguide Model for Parabolic Index Planar Segmented Waveguides
(1995)
In this paper we outline a simple procedure to obtain an equivalent z-invariant waveguide for a given graded index segmented
waveguide. In particular, the proposed model is shown to predict accurately the modal spot size ...
Evolution of the intensity profile of Cerenkov second-harmonic radiation with propagation distance in planar waveguides
(1996)
Using coupled mode theory, we have studied the output intensity profile of Cerenkov second-harmonic radiation from planar waveguides as a function of the propagation distance. In particular, we have obtained the variation ...
Characterization and simulation of long period gratings fabricated using electric discharge
(2001)
We report the characterization and theoretical simulation of long period gratings fabricated using electric arc discharge in two different fibers namely, SMF-28 (Δ=0.0036) and DSF (Δ=0.009). We show that this technique can ...
Dispersion compensation in transmission using uniform long period fiber gratings
(2001)
It is proposed that the high dispersion at the transmission band edges of uniform long period gratings (LPG) fabricated on relatively high Δ fibers can be used for efficient dispersion compensation. Since the transmission ...
Conception, realization, and characterization of a very high negative chromatic dispersion fiber
(2001)
After a brief presentation of many possible solutions usable to control or compensate the chromatic dispersion of optical links, we report the simulation, realization, and characterization of a dual asymmetric core dispersion ...
A study on the performance of L-band EDFAs under different pumping configurations
(2001)
In this letter, we investigate and compare theoretically the performance of an optimized L-band erbium doped fiber amplifier when an L-band erbium doped fiber (EDF) or an optimized C-band EDF, is used separately as an ASE ...
A novel design of an intrinsically gain flattened erbium doped fiber
(2000)
In this paper, we propose a novel coaxial dual-core erbium doped fiber profile characterized by an intrinsically flat gain
spectrum. It is shown that by doping only the outer core, it is possible to achieve gain flattening ...
Vector modes of an optical fiber in the weakly guiding approximation
(1989)
The authors show that starting from the appropriate linear combinations of LP modes, the weakly guiding approximation of the hybrid modes can be easily obtained without any reference to the rigorous vector modes. The ...
Estimation of cut-off wavelength of rare earth doped single-mode fibers
(1999)
A new empirical relation is proposed describing spectral variation of mode-field radius MFR as inferred from measurements in the far-field of the fiber. It is shown that using this relation, it is possible to estimate the ...
