Abstract
An optical power and wavelength monitor of an optical beam is described. The monitor includes a first detector positioned in the path of the optical beam that generates a first electrical signal that is proportional to an optical power of the optical beam. The monitor also includes an optical filter that is positioned in the path of the optical beam. The optical filter transmits a portion of the optical beam having a wavelength within a bandwidth of the optical filter. A second detector that is positioned in the path of the optical beam generates a second electrical signal that is proportional to an optical power of the filtered optical beam. A signal processor receives the first and second electrical signals and generates a signal that is proportional to the wavelength of the optical beam.
