An electromagnetic wave propagating along a path C has the phase shift over C as if it was propagating a path in a vacuum, length of which, is equal to the optical path length of C. Thus, if a wave is traveling through several different media, then the optical path length of each medium can be added to find the total optical path length. The ...
Optical path (OP) is the trajectory that a light ray follows as it propagates through an optical medium. The geometrical optical-path length or simply geometrical path length ( GPD ) is the length of a segment in a given OP, i.e., the Euclidean distance integrated along a ray between any two points.

Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of photon movement between sites of photon-matter interaction and the angles of deflection in a photon's trajectory when a scattering event occurs.
This algorithm calculates the shortest path using the number of optical routers as the cost function. A single probe is used to establish the connection using the shortest path. The running time is the cost of Dijkstra's algorithm: O ( m + n log n ) {\displaystyle O(m+n\log n)} , where m {\displaystyle m} is the number of edges and n ...
An optical system that produces no net convergence or divergence of the beam, i.e. has an infinite effective focal length. [7] This type of system can be created with a pair of optical elements where the distance between the elements is equal to the sum of each element's focal length ( d = f 1 + f 2 {\displaystyle d=f_{1}+f_{2}} ).

When a lightpath can be established between source and destination node endpoints the connection is totally optical and avoids throttling by intermediate electronic conversions and processing. [1] Where a lightpath passes through an Optical add-drop multiplexer (OADM) is known as a cut-through lightpath .
