Abstract: An optical communication system using a photonic lantern for fine point tracking is disclosed. The optical communication system may comprise a photonic lantern, a signal processing unit including one or more fiber splitters to sample a fraction of a received signal in each single mode fiber of the photonic lantern, and one or more intensity sensors positioned in one arm of each fiber splitter, and used for monitoring fiber-specific intensity data associated with each of the single-mode fibers. The system may further include a fine pointing assembly and a controller for controlling a driver of the fine pointing assembly.

Abstract: An optical system includes a plurality of internal apertures, a plurality of external optical assemblies and a telescope assembly positioned between the plurality of internal apertures and the plurality of external optical assemblies. Each internal aperture is operable to receive a corresponding aperture-specific optical signal. Each external optical assembly corresponds to one of the internal apertures, and each external optical assembly is operable to direct the aperture-specific optical signal of the corresponding internal aperture in a corresponding external direction. The external direction for each external optical assembly is independently controllable and the telescope assembly defines a shared optical train arranged to direct the aperture-specific optical signals between each internal aperture and the corresponding external optical assembly.

Abstract: An apparatus (100) for optical pointing is disclosed. The apparatus comprises a telescope (120, 122, 124, 126), a transmission prism (114) rotatably coupled to the telescope, and a rotatable mechanism (132, 136) operatively coupled to the telescope. The transmission prism is configured to rotate around a first rotation axis (116), and the rotatable mechanism is configured to rotate around a second rotation axis (144) that is different than the first rotation axis.
