We provide benchtop SLED broadband light sources that cover the wavelength from 400nm to 1620nm. SLED sources have higher output power density compared to LED sources. They can be used to test optical components, systems or links, or used as incoherent broadband light source for applications in optical sensoring, spectrum slicing, and microwave photonics.

1140nm SLED Broadband Light Source
Central Wavelength (nm):
Each SLED Broadband Light Source Fiber laser Source has a central wavelength, from 400nm to 2000nm. And we will have other wavelengths in future.
In telecommunications, spectral width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value.
In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most −3 dB).
The FWHM method may be difficult to apply when the spectrum has a complex shape. Another method of specifying spectral width is a special case of root-mean-square deviation where the independent variable is wavelength, λ, and f (λ) is a suitable radiometric quantity.
The relative spectral width, Δλ/λ, is frequently used where Δλ is obtained according to note 1, and λ is the center wavelength.
Output Power (mW):
Each SLED Broadband Light Source Fiber laser Source has an output power. It depends on the application in which it will be used.
Spectral Density Stability < +- 0.05dB/15 min. :
The power spectrum of a time series describes the distribution of power into frequency components composing that signal.According to Fourier analysis, any physical signal can be decomposed into a number of discrete frequencies, or a spectrum of frequencies over a continuous range. The statistical average of a certain signal or sort of signal (including noise) as analyzed in terms of its frequency content, is called its spectrum. Spectral Density Stability is the stability for Spectral Density.
Short Term Stability < +- 0.01dB/15 min.
Long Term Stability < +- 0.05dB/15 min.
