Janus-Core and Shell Microfibers

Langmuir, 2013
Janus 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.

Reef Knot Microfiber Resonators

Asia Optical Fiber Communication and Optoelectronic Exposition and Conference, 2008
We 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, 1977
An 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, 2008
Measurements 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 ...

Microfiber Resonator in Polymer Matrix

IEICE Transactions on Electronics, 2007
We 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.

Capturing microfibers – marketed technologies reduce microfiber emissions from washing machines

Marine Pollution Bulletin, 2019
Microfibers are a common type of microplastic. One known source of microfibers to the environment is domestic laundering, which can release thousands of fibers into washing machine effluent with every wash. Here, we adapted existing methods to measure the length, count and weight of microfibers in laundry effluent.

Fused Microfiber Resonators

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
We demonstrate a ∼2.6 mm-diameter optical ring resonator fabricated from a 7.2 µm-thick silica fiber with a CO 2 laser- fused coupling region for mechanical robustness. We experimentally obtain a Q-factor of ≥25,000 at 1.55 µm.

Engineered Microfibers for Tissue Engineering

ACS Applied Bio Materials
Hydrogel 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), 2017
This 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
