摘要： An Optical Tapped Delay Line (OTDL), which resolves multiple wavelength signals having extremely narrow wavelength spacing, is combined with other known optical devices to provide a wide variety of optical processing application, including: multiplexing and de-multiplexing a multi-channel signal; adding a signal to, or dropping a signal from, a multi-channel optical signal; specialized coding processing such as generating code division multiple access signals; wavelength locking (stabilizing) a signal; filtering a signal; and analyzing and monitoring a signal spectrum. The OTDL (247) spatially separates individual channels to allow separate processing on each channel. The devices and processes disclosed have particular application to dense wavelength division multiplexing (DWDM) and permit a significant improvement in the quantity of information that can be carried on DWDM signals while enhancing signal quality.
