Abstract: An apparatus comprising: a void; an interferometer detector; and



light guide means for guiding a light signal along a light path to the interferometer detector wherein the light path comprises a cantilever light guide that is supported such that a free-end can move within the void and the interferometer detector is configured to detect a deflection of the free-end of the cantilever light guide; and
a reflector, wherein the cantilever light guide comprises a light outcoupler configured to out-couple the light signal to extend the light path from the cantilever light guide to the reflector.

Abstract: An apparatus with a first photodetector and a second photodetector is provided. The apparatus is configured to receive light, and the first photodetector is configured to detect a first portion of the light. The first photodetector and the second photodetector are in a stacked arrangement and the apparatus is configured to pass a second portion of the light through the first photodetector to the second photodetector. The apparatus further includes an optical blocking filter configured to filter the second portion of the light prior to the second portion of the light arriving at the second photodetector.

Abstract: An apparatus may include an optical combiner configured to combine a first optical beam having an adjusted first polarization with a second optical beam having an adjusted second polarization into an output beam having a third polarization. The third polarization may be a linear combination of the adjusted first polarization and the adjusted second polarization. Information may be communicated by adjusting the polarization according to an information source.

Abstract: Methods and apparatuses, including computer program code are disclosed. The apparatus may include at least one processor and at least one memory including computer program code. The at least one processor, the at least one memory, and the computer program code may be configured to cause the apparatus to generate a divergent beam for an optical source that is coincident with a divergent beam for an optical detector. The apparatus may determine an adjustment to a mirror to cause an optical alignment of an incoming beam with the optical detector based on at least an optical intensity across the optical detector, wherein the alignment is with respect to at least another apparatus. The apparatus may adjust a position of the mirror according to the determined adjustment, and change the divergent beam to a collimated beam to enable optical communications with the other apparatus via the collimated beam.
