... The choice of wavelength depends upon the loss profile of the medium. For optical fiber the wavelength has to be 1300nm or 1550nm for low loss. The spectral width has direct bearing on the data rate which the medium can support. Larger the spectral width, smaller is the data rate. A semiconductor la ...

The cost of using a farther detuned laser (longer wavelength) is that it will require greater power to create a sufficiently deep trap. Lasers from six different companies were compared in or ...

Moreover, if their wavelengths are in the fiber’s lowloss propagation window near 1.5 µm, the transmission losses can be minimized. Such a source has been recently developed by exploiting th ...
