Abstract :
We present the concept of using image plane transformations with free-space diffraction-grating-based multiplexers. We demonstrate two examples of a diffraction-grating-based multiplexer that take advantage of image plane spatial transformations. We show that the use of such spatial transformations has unique advantages for multiplexing schemes. We also demonstrate unique system applications enabled by these multiplexers.
