摘要	A high power optical combiner (18) is provided for amplifying an optical signal. The combiner (18) includes a splitter (20) having a splitter input (22)and two splitter outputs (24, 26). The splitter input (22) receives an optical signal which the splitter divides (20) into two sub-signals. The splitter outputs (24, 26) have respectively coupled thereto a reference arm (30) and a dither arm (32). Both arms (30, 32) receive the sub-signals from the respective splitter outputs (24, 26) and transmit the sub-signals in parallel. Each arm (30, 32) has an amplifier (34) integrated therein for amplifying the sub-signals in parallel thereby producing amplified sub-signals. The high power optical combiner (18) further includes a combining coupler (42) connected to both arms (30, 32). The combining coupler (42) has two coupler inputs (46, 48), and a coupler output (50). The coupler inputs (46, 48) receive the amplified sub-signals from the arms (30, 32). The combining coupler (42) constructively combines the amplified sub-signals to produce a primary amplified signal that is transmitted through the coupler output (50). The coupler output (50) has a dither tap coupler (58) attached thereto for drawing a secondary amplified signal from the primary amplified signal. The secondary amplified signal is coupled to a phase controller (52) and a polarization controller (54), both of which are coupled to the dither arm (32) between the splitter (20) and the amplifier (34). These controllers (52, 54) respectively adjust the phase and the polarization of the sub-signal in the dither arm (32) to allow for efficient combination of the amplified sub-signals.
