WAVELENGTH DIVISION MULTIPLEXING COUPLER WITH LOSS ELEMENT |
摘要 |
A method and system for adjusting power at output ports of a wavelength division multiplexing (VVDM) coupler (12). A loss element (14) may be placed at one or more of the output ports (20, 22) of the WDM coupler. The loss element (14) may have a filter characteristic that compensates the temperature sensitivity coefficient of the WDM coupler (12). The filter characteristic may reject power at one of the two output ports as a function of temperature. As a result, the loss element may balance the power at the output ports (20, 22) of the WDM coupler (12) despite temperature variations. |
