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 ...

The authors conduct a numerical analysis of optical fibers characterized by arbitrarily graded, cylindrically symmetric refractive index profiles by transforming them into equivalent planar profiles and using a matrix ...

We present a simple analytical method to study birefringence and polarization mode dispersion (PMD) of elliptic-core fibers with uniform or differential stress in the fiber cross section. The model takes account of both ...

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 ...

By incorporating an isolator at an appropriate location, it is shown that it is possible to realize an efficient single-pass superfluorescent-doped fiber source with a major fraction of its emitted power in the forward ...

We report here a novel fiber design which has inherently flattened effective Raman gain spectrum, with a relative 3-dB bandwidth of /spl sim/90 nm. Gain-flattened broad-band amplification can be achieved in any wavelength ...

A new waveguide structure with periodycilly segmented cover and substrate regions and a uniform film region is proposed.This complementary segmented waveguide is analysed in terms of the effective index and the spot size ...

A numerical technique that allows straightforward determination of bound-state and quasi-bound-state energy eigenvalues (and lifetimes of the latter) for arbitrary one-dimensional potentials is presented. The method involves ...

In this correspondence we have developed the perturbation approach for the calculation of propagation constants for some of the practical slab waveguides and have shown the applicability of the approach to systems of ...

A simple matrix approach, which involves multiplication of 2×2 transfer matrices, is developed to study the propagation characteristics of a nonlinear planar waveguide. Numerical results for some nonlinear structures are ...
