Abstract
An optical splitting device is intended to receive at an input two beams of different wavelengths. The device includes a polarizing beam splitter designed to selectively transmit part of the beam having one of the wavelengths towards a first output or a second output depending on the polarization of said beam. The device further includes a polarization variation system placed upstream of the polarizing beam splitter. By combining the polarization variation device with the polarizing beam splitter it is possible to adjust the distribution of the energy of a beam between the two outputs of the device. Such a splitting device is advantageously incorporated into an optical communication terminal.
