We report on the experimental observation of coherent cavity soliton frequency combs in silica microspheres. Specifically, we demonstrate that careful alignment of the microsphere relative to the coupling fiber taper allows for the suppression of higher-order spatial modes, reducing mode interactions and enabling soliton formation. Our measurements show that the temporal cavity solitons have su...

the main objective of this study was to investigate biocompatibility and provide in vivo pharmacological and toxicological evidence for further investigation of the possibility of ph sensitive ion exchange resin microsphere for clinical utilizations. acute toxicity study and general pharmacological studies were conducted on the ph sensitive ion exchange resin microsphere we prepared. the genera...

We report a simple method to fabricate two-dimensional (2D) periodic non-close-packed (ncp) arrays of colloidal microspheres with controllable lattice spacing, lattice structure, and pattern arrangement. This method combines soft lithography technique with controlled deformation of polydimethylsiloxane (PDMS) elastomer to convert 2D hexagonal close-packed (hcp) silica microsphere arrays into nc...

The diffraction limit is a fundamental barrier in optical microscopy, which restricts the smallest resolvable feature size of microscopic system. Microsphere-based microscopy has proven to be promosing tool for challenging limit. Nevertheless, microspheres have low imaging contrast air, hinders application this technique. In Letter, we demonstrate that challenge can effectively overcome by usin...

Accurate calculation of internal and surface scattering losses in fused silica microspheres is done. We show that in microspheres internal scattering is partly inhibited as compared to losses in the bulk material. We pay attention on the effect of frozen thermodynamical capillary waves on surface roughness. We calculate also the value of mode splitting due to backscattering and other effects of...

At the onset of a miniaturized device era, several promising methods, primarily wet have been developed to attain large-scale assemblies microparticles. To improve speed, versatility and robustness current methods for structured assembly microparticles, an automatable method capable forming 2D arrays microspheres on large silicon surfaces is devised. The uses perforated with vacuum-suction hole...

Optical frequency combs generated in whispering gallery mode microresonators are high demand for basic science and a large number of applications including telecommunication systems quantum optics. Here, we study experimentally theoretically optical comb generation silica microsphere with zero dispersion wavelength near $1.55 μm pumped by continuous wave laser widely tunable the C-band. We cons...

tion (AMD), glaucoma, dry eye and diabetic retinopathies is increasing steadily. Drug treatment for ocular diseases is challenging due to the complex and protected structure of the eye, which prevents the penetration of active compounds at the site of action, e.g. the retina, after systemic administration. Although topical administration of eye drops is an easy and non-invasive method of ocular...
