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.
