Abstract
An optical circulator couples optical fibers of dissimilar modes. In one embodiment, an optical circulator couples a single mode first fiber to a multimode second fiber, which is used as an optical input to a telescope. The multimode fiber does not significantly degrade the mode structure of the light form the single mode fiber. In the reverse direction, light received by the telescope is coupled into the multimode second fiber, which the circulator couples to a multimode third fiber.
