Abstract
An optical wavelength multiplexing device for use in an optical networking environment is presented. The device features optically dispersive elements combined with an array of reflectors that permit both realization of flat-top filter characteristics together with noise reduction, and in some embodiments wavelength routing, blocking or add-drop functionality. Additionally, the design of the device is easily modified to dissipate light having a wavelength that does not correspond to any predetermined wavelength channel.
