Janus-Core and Shell Microfibers
Langmuir, 2013Janus microcylinders composed of different polymers were prepared through coaxial co-jetting with dual-core flows, followed by cross-linking, microsectioning, and shell removal. Uniquely shaped building blocks can be fabricated by photo-patterning of one hemisphere of the microcylinders.

Optical data storage in microfibers
Optics Letters, 1998Tests of optical data storage in arrays of microfibers confirm its applicability and potential for higher storage densities than those achievable with conventional holographic data storage. Arrays of single-mode microfibers, spaced 0.78 microm apart and 60 microm long, were generated in a photopolymer film with four laser beams and simultaneously ...

Reef Knot Microfiber Resonators
Asia Optical Fiber Communication and Optoelectronic Exposition and Conference, 2008We propose a new way to realize a microresonator by making a reef knot with two microfibers. We demonstrate an all-silica reef knot resonator and discuss the first steps towards hybrid silica-chalcogenide resonators.

Neonatal ophthalmoplegia with microfibers
Neurology, 1977An infant born with marked hypotonia showed prompt regression of skeletal muscle weakness, but by 7 weeks of age had total external ophthalmoplegia. Biopsy of the gluteus muscle at 14 days showed marked variation in fiber size with a large proportion of very small fibers (less than 3 mu).

Observation of a nonlinear microfiber resonator
Optics Letters, 2008Measurements of the intensity transfer function of a silica microfiber resonator are shown to follow a wide variety of hysteresis cycles, depending on the cavity detuning and the scanning frequency of the range of input powers. We attribute these observations to a nonlinear phase shift of thermal origin and provide a simple model that reproduces well ...

Highly birefringent silica microfiber
Optics Letters, 2010A highly birefringent silica microfiber was successfully developed by adiabatically tapering a low-birefringence flat fiber at a low temperature. Owing to the high fiber cross-sectional ellipticity and the large refractive index contrast between silica and the surrounding air (deltan=0.45) the flat microfiber provides an extremely high group ...

Microfiber Resonator in Polymer Matrix
IEICE Transactions on Electronics, 2007We propose a simple technique to form miniature optical circuits using microfibers embedded into a low refractive index matrix. As an example we demonstrate a silica microfiber knot resonator embedded in a fluoroacrylate polymer. Fabrication issues and initial experimental results are reported.

Engineered Microfibers for Tissue Engineering
ACS Applied Bio MaterialsHydrogel microfibers are hydrogel materials engineered into fiber structures. Techniques such as wet spinning, microfluidic spinning, and 3D bioprinting are often used to prepare microfibers due to their ability to precisely control the size, morphology, and structure of the microfibers. Microfibers with different structural morphologies have different

Hydrogel microfibers for biochemical applications
2017 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2017This paper describes fabrication and applications of stimuli-responsive hydrogel microfibers for biochemical sensors and actuators. Our group has developed stimuli-responsive hydrogel microsprings (SR springs) for mugnifying the shrink/swell movements. The SR springs, made of composite hydrogel of p(NIPAM-co-AAc) and calcium alginate, were continuously
