DEVICE AND METHOD FOR OPTICALLY CONVERTING WAVELENGTHS FROM AN ELECTROABSORPTION MODULATOR

摘要

The invention relates to the conversion of wavelengths, particularly for telecommunications applications, from an electroabsorption modulator (MEA) comprising: two inputs for respectively receiving a pump signal (SP) modulated to a first optical wavelength ?<SUB>p </SUB> and a continuous probe signal (SS) having a second optical wavelength ?<SUB>s</SUB>, and; an output furnishing a converted signal (SC) representing the modulations of the pump signal having, in particular, wavelength ?<SUB>s</SUB>. According to the invention, a band-pass filter (FBP) is provided that is applied to the output of the electroabsorption modulator and centered on a wavelength especially offset with regard to the second wavelength ?<SUB>s</SUB>.
