Abstract

An optical excursion device (15) comprising a channel waveguide (2) having a channel optical axis (7), a first mirror (9) and second mirror (11) is described. The first (9) and second (11) mirrors tend angles relative to the channel optical axis (7) that exhibit substantially equal magnitudes and orientations. This mirror arrangement results in the coupling of an optical signal reflected out of an input section of the channel waveguide (2), and thereafter back into an output section of the channel waveguide (2), not being critically dependent on the absolute angle between the mirrors, (9) and (11), and the channel optical axis (7). A further advantage is that the first (9) and second (11) mirrors can be located upon a common surface. As a result the manufacturing tolerance levels of the optical excursion device (15) are significantly reduced when compared to those known in the art.
