Abstract: A waveguide includes a segment with a substantially uniform cure profile and related methods and systems for making and using the same. The waveguide is formed by modifying a laser beam used to write the waveguide to provide a substantially uniform cure profile in the waveguide. A marker characteristic of laser writing may be present in the waveguide.

A convolution compensator is positioned in the path of the laser beam to modify the beam spot profile during writing to form the one or more segments of the waveguide in a photo-curable layer.

Abstract: A system includes a first optical communication interface and a second optical communication interface optically coupled via a free-space communication channel. The interfaces are spaced at variable distances. Each interface includes an optical source to provide a beam of electromagnetic energy and an optical receiver to receive the beam to bi-directionally communicate with the other interface via the channel. The first optical communication interface may be coupled to a sub-chassis. The second optical communication interface may be coupled to a device frame. The device frame may be movably coupled to the chassis. Communication may utilize multi-input, multi-output processing configured by a calibration matrix. A shutter may be positioned to receive the beam or be positioned clear of the beam depending on the distance between the interfaces.
