Wavelength creates Color objects given the wavelength or the frequency of the light rather than the usual RGB or HSB. instead of: Color c = new Color(255, 0, 0); use the frequency in nanometers, and gamma 0.0. .. 1.0. (gamma is intensity/brightness.) Color c = Wavelength.wvColor( 400.0f, 0.80f ); The visible range of the spectrum is 380..780 nanometers. Smaller is bluer. or using frequency in Terahertz and gamma 0.0. .. 1.0. Color c = Wavelength.fColor( 500.0f, 1.0f ); The visible range of the spectrum is 384..789 TeraHertz. Smaller is redder. Wavelength does not do much on its own. It is intended to be incorporated into your own programs.

This function will calculate the wavelength of a given frequency. By default the program will presume the entered value is in MHZ. However if you want to enter a frequency in another scale you also have the option to enter the scaling parameter as well (khz,mhz, or ghz). function call: lambda(frequency) || lambda(30) lambda(freq,'scale') || lambda(30,'ghz') current scale options: 'khz' 'mhz' 'ghz'.

- Pyanpha
- License: Freeware

Pyanpha was developed as a shell-based tool that manages to apply the multi-wavelength anomalous diffraction technique to Surface Diffraction.
Pyanpha enables one to calculate the phases of the structure factors of crystal truncation rods when anomalous scatterers are present in the thin film.
Functionality extends to standalone simulations. It was coined Pyanpha which is an acronym for PYthon ANomalous PHAsing and it is written in Python.

- WDM Network Blocking Computation Toolbox
- License: Freeware

The aim of this toolbox is to compute blocking probabilities in WDM networks. This work was based on [1], [2], [3], [4] and user is referred to those papers for deeper study. Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources. Also in circuit switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion.

- Fabry Perot filter modeling and Analysis
- License: Freeware

A Fabry-Parot Filter consist of the cavity formed by two highly reflective mirrors placed parallel to each other , as shown in the figure 1.The input light beam to the filter enters the first mirror at right angles to its surface. The output of the filter is the light beam leaving the second mirror. This filter is called Fabry-Parot or etalon. This is a classical device that has been used widely in interferometric applications. Fabry-Parot filters have been used for WDM in several optical network test beds. There are better filters today, such as thin film resonant multi cavity filter and they can still be viewed as Fabry-Perot filter.

- Envelope
- License: Freeware

This function begins by deducing the wavelength of the signal's primary Fourier component. It then smooths the signal using a moving-window average -- the window is roughly top hat, of size equal to the primary wavelength. For 2-D data it will perform this function on each column of data, using the primary wavelength of the central column throughout. The only input is the oscillating field. This method works remarkably well in obtaining the laser field envelope from the particle-in-cell simulations I have tested it on (see screenshot). A possible extension would be to adapt it for a signal with a time-dependent frequency, by implementing a window of position-dependent size.

Split the signal S(SPACE,TIME) into its downward/upward space propagating and stationnary components via a 2D Fourier decomposition. S is a (SPACE,TIME) matrix. We eventually proceed to a space and/or time filtering. DT,DX are temporal and space step. PERIOD=[Tmin Tmax] and WAVELENGTH=[Xmin Xmax] are time and space band-pass filters specifications..

- Drude-Lorentz and Debye-Lorentz models for the dielectric constant of metals and water
- License: Freeware

This code computes the complex dielectric constant (i.e. relative permittivity) and the refractive index of various metals using either the Lorentz-Drude (LD) or the Drude model (D) as a function of input light wavelength. Additionally, it may compute the dielectric constant of pure water using a Debye-Lorentz model. Choice of materials: silver, aluminum, gold, copper, chromium, nickel, tungsten, titanium, beryllium, palladium, platinum, triply distilled water.

- MatPlanWDM v0.5
- License: Freeware

MatPlanWDM is a network planning tool for wavelength-routing WDM networks. The input parameters to the planning problem are the network physical topology, the traffic matrix, and technological constraints like the number of transmitters, receivers, optical converters and wavelengths available. It includes a set of heuristic algorithms for solving the virtual topology design, and the routing and grooming of traffic flows on top of it. The set of heuristic algorithms can be extended. This is eased by a set of libraries of classical network optimization algorithms included in the tool. In addition, an implementation of the linear mixed-integer programming (MILP) problem to obtain the optimal solution is also included.

- Diffraction grating
- License: Freeware

A collection of m-files aimed at learning and teaching about the principles of diffraction gratings. Some of these show a cross section of the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry. Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order. Others demonstrate how grating operation arises from the interference of reflections from multiple grooves. For more details, see http://www.wam.umd.edu/~toh/models/matlab/...tionGrating.

- WallEffect
- License: Freeware

Simulates the wall effect in a gaseous thermal neutron detector with a gaseous neutron converter (He-3) using the Monte Carlo method. Based on the gap thickness (in m) and the partial pressure of helium-3 (in bar), this program computes the fraction of events that suffers to some extent from the wall effect in the detector, i.e. one or both of the secondary particles hits the wall of a planar detector. It also outputs the efficiency of the detector, neutron wavelength 0.18 nm..

BlackBody accepts temperature as input and returns total radiance and peak radiance. If wavelengths are also input, spectral radiance and number of photons are also included in the output. If a wavelength range is input, then the total radiance and number of photons within that range are calculated. Output is in a structure, or nicely printed if no output variables are defined by the calling function..
