ABSTRACT:
The invention provides a coupling device for monochromatic optical signals based on the amplitude division method. The optical signal emerging from one light guide is divided by means of one or more diffraction gratings among three or more outgoing light guides. Inversely, the optical signals from a number of light guides can be combined into one optical signal. Such a coupling device has a high optical efficiency, is mode-independent and produces small differences in light intensity between the branch signals.
