Linewidth wavelength to frequency

Nettetfrequency with zero linewidth. In a real world, however, a laser has a finite linewidth because of phase fluctuation, which causes instantaneous frequency shifted away from the central frequency: δν(t) = (1/2π) dφ/dt. Linewidth Laser linewidth is an important parameter for characterizing the purity of wavelength (frequency) and coherence of a NettetThe WDM technique of channel multiplexing employ a narrow line-width laser (such as a distributed feedback (DFB) semiconductor laser) for each channel. The carrier frequencies of two neighboring channels should differ by an amount known as the channel spacing, typically in the range of 25 to 100 GHz.
