Abstract

An optical device (1) having a shutter selectively moveable in and along a trench defined between an input waveguide (3) and an output waveguide (3). Each waveguide (3, 5) has a core (27) defined therethrough that defines an optical path through the device and which traverses the trench (15). The trench (15) intersects the optical path and the shutter (17) may be moved into and out of the optical path or within the optical path. By selectively moving the shutter (17) into and out of the trench (15), and into and out of the optical path, an optical signal propagating in and through the waveguide (3, 5) may be conditioned. The shutter (17) may be sized and shaped to attenuate an optical signal passing through the trench (15) when the shutter intersects the optical path. Alternatively, the shutter (17) may have at least one aperture defined therethrough to provide chopping of an optical signal passing through the trench (15) by selectively moving the shutter in the trench )15) so as to alternatively block the optical signal and allow the optical signal to pass from one waveguide (3, 5) to the other.
