  1. Tunable Light Source Fiber optic By Mays Moafaq

  2. Tunable Light: Definition :it is a manipulation in the input signal so the output would have different wavelengths of an optical device such as a laser. For some applications, it is required that the wavelength of an optical device can be tuned within some range. There are two common types of Tunable light sources: 1-Tunable-laser. 2-Tunable-LED.

  3. Tunable-Laser: A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. There are many types and categories of tunable lasers. They exist in the gas, liquid, and solid state. Among the types of tunable lasers are, CO2 lasers, dye lasers (liquid and solid state), transition metalsolid-state lasers, semiconductor crystal and diode lasers, and free electron lasers. Tunable lasers find applications inspectroscopy, photochemistry, atomic vapor laser isotope separation, and optical communications.

  4. Tunable-LED: It is a Visible-color-tunable light-emitting diodes (LEDs) that changes continuously from red to blue by adjusting the external electric bias are fabricated. It is operating at a fixed drive current.
