A device for directing one or more optical channels includes one or more micromirror elements. A micromirror element has a mirror and a mirror controller. The mirror is operable to reflect light at a first interaction area to yield a first passband for an optical channel, and to reflect light at a second interaction area to yield a second passband for the optical channel. The mirror controller operates to position the mirror at a first position at which light interacts with the first interaction area to yield the first passband, and to position the mirror at a second position at which light interacts with the second interaction area to yield the second passband.
