摘要：An example demultiplexer may include at least one dispersive element that is
common to multiple wavelength channels. The demultiplexer may additionally includemultiple field lenses positioned optically downstream from the at least one dispersiveelement, where a number of the field lenses is equal to a number of the wavelengthchannels. An example multiplexer may include a single piece power monitor assemblythat includes a collimator lens array, a focusing lens array, and a slot integrally formedtherein. The collimator lens array may be positioned to receive multiple wavelengthchannels from a laser array. The focusing lens array may be positioned to focus multipleportions of the wavelength channels onto an array of photodetectors. The slot may beconfigured to tap the portions from the wavelength channels collimated into the singlepiece power monitor assembly by the collimator lens array and to direct the portionstoward the focusing lens array.
