Using the electrical engineering notation, we re-derive a formulation for a recently proposed parallel algorithm for the simulation of pulse propagation through a single mode optical fiber. The meaning of the change of variables in the original derivation has been explained, the performance of the re-derived parallel algorithm is probed when used in digital post compensation of the dispersive and...
An orthogonal ray graph is an intersection graph of horizontal and vertical rays (half-lines) in the xy-plane. An orthogonal ray graph is a 2-directional orthogonal ray graph if all the horizontal rays extend in the positive a;-direction and all the vertical rays extend in the positive x-direction. We show several characterizations of 2-directional orthogonal ray graphs. We first show a forbidden...
