<p>An optical splitter for use in an optical system. The optical splitter comprises one or more reconfigurable holographic diffraction gratings(106) for selectively splitting one or more input signals (102) into two or more split signals (107), two or more optical pumps (115) for generating two or more pump signals (117), and two or more optical amplifier outputs (119) for respectively receiving the split signals and the pump signals and amplifying the split signals to a predetermined power level in response to the pump signals. The reconfigurable holographic diffraction gratings (106) are operable to selectively couple the split signals (107) to the optical amplifier outputs (119). A method of controlling the output power of split optical signals is also described.</p> |
