摘要：
According to an aspect of the present invention, a circuit is provided for determining the wavelength and power of a given optical signal across a wide dynamic range. The wavelength and power determinations are performed by logarithmic ratio amplifier in concert with a digital signal processor that utilizes representative equations of the measured optical signal.
