Optical Microtube Ring Resonators
AIP Conference Proceedings, 2007In this work, we demonstrate that semiconductor microtubes fabricated by utilizing the self‐rolling mechanism of epitaxially grown strained bilayers can act as optical ring resonators. The mode structure is probed by the photoluminescence of an optically active material, i.e. self‐assembled quantum dots, embedded inside the microtube wall.

We have studied structures where a concentric ring with an index higher than that of the cladding index is added to a conventional fiber core. The structure supports at least one additional symmetric mode with substantial power in the ring, besides the normal mode in the core.

Subwavelength nanoplasmonic ring resonators
Journal of the Optical Society of America B, 2005Electromagnetic ring resonators composed of noncontacting metal nanoparticles are analyzed as building blocks of future plasmonic optical systems. Closed-form expressions for the electromagnetic modes are obtained, and conditions under which such structures exhibit low or high radiative losses are found.

Expressions are derived for the stability parameter, spot size, and wavefront curvature of a Gaussian beam in a ring resonator containing up to four spherical mirrors unequally spaced. Higher-order transverse modes and aperture effects are not considered.
