  2. Optical path length - Wikipedia

    en.wikipedia.org/wiki/Optical_path_length

    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 ...

  3. Optical path - Wikipedia

    en.wikipedia.org/wiki/Optical_path

    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.

  4. Routing and wavelength assignment - Wikipedia

    en.wikipedia.org/wiki/Routing_and_wavelength...

    Fixed path routing is the simplest approach to finding a lightpath. The same fixed route for a given source and destination pair is always used. Typically this path is computed ahead of time using a shortest path algorithm, such as Dijkstra's Algorithm. While this approach is very simple, the performance is usually not sufficient.

  5. Monte Carlo method for photon transport - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_method_for...

    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.

    In addition, OSLO is used to simulate and analyze the performance of optical systems. OSLO's CCL (Compiled Command Language), which is a subset of the C programming language, can be used to develop specialized optical and lens design software tools for modeling, testing, and tolerancing optical systems.

    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}} ).
