High-accuracy finite-difference equations for dielectric waveguide analysis I: uniform regions and dielectric interfacesJournal of Lightwave Technology - Tập 20 Số 7 - Trang 1210-1218 - 2002
G.R. Hadley
A methodology is presented that allows the derivation of low-truncation-error
finite-difference representations or the two-dimensional Helmholtz equation,
specific to waveguide analysis. This methodology is derived from the formal
infinite series solution involving Bessel functions and sines and cosines. The
resulting finite-difference equations are valid everywhere except at dielectric
corners, a... hiện toàn bộ

Improved 60/spl deg/ bend transmission of submicron-width waveguides defined in two-dimensional photonic crystalsJournal of Lightwave Technology - Tập 20 Số 7 - Trang 1198-1203 - 2002

We compare quantitatively the transmission properties of various 60/spl deg/
bends carved into a photonic crystal based on a two-dimensional triangular
lattice of holes perforating a GaAs-based heterostructure. The bends are
inserted into channel waveguides defined by three missing rows in the photonic
crystal. Their design is inspired by some ideas from classical integrated
optics. We show experi... hiện toàn bộ

Experimental and theoretical characterization of a 40-Gb/s long-haul single-channel transmission systemJournal of Lightwave Technology - Tập 20 Số 7 - Trang 1124-1131 - 2002

We present a comparison between experiment and simulation of a 40-Gb/s
periodically stationary dispersion-managed soliton (DMS) system in a
recirculating loop. We find that we can propagate an error-free signal over 6400
km at 40 Gb/s and over 12 000 km if we lower the data rate to 10 Gb/s, keeping
all other parameters constant. A careful analysis of the limiting factors shows
the strong influence... hiện toàn bộ
