ABSTRACT:
An integrated optical-power adjustable WDM is provided, which has a plurality of channels, each channel having a first input port, a second output port and a third output port, the second output port of one channel being connected to the first output port of the next channel, the first port of each channel having a waveguide, the third port of each channel having a waveguide, each channel comprising a pair of collimating elements composed of a first collimating element and a second collimating element, a thin film filter and a tunable optical filter chip functioning as a variable optical attenuator, wherein the tunable optical filter chip is set between the thin film filter and the third output port for each channel, thereby the respective tunable optical filter chip is integrated into the corresponding internal optical path for each channel of WDM to achieve optical-power control for each channel of the WDM.
