Design of fiber stick chips and its application to the Michelson interferometer

A novel fiber stick chip is designed by assembling and stacking functional fiber sticks as building blocks. Stick components in this optoelectronic packaging are composed of two types of fiber-like sticks. The first type consists of the functional short optical fibers used for amplifying, filtering, or interconnecting. The second type includes shape memory alloy sticks used for switching and phase-shifting. Referring to the optical circuit; the right-angled fiber-to-fiber coupling, the side-by-side coupling, the transverse propagating, and the optical power dividing all play an important role in the 2 or 3-dimensional interconnecting. Two examples, including Michelson interferometer chips, are shown.
