Recently we have investigated the possibility of fabricating optically active microstructures which may potentially be of use in future photonic or optoelectronic circuits. As a first step in this direction we demonstrated the concept of a whispering-gallery mode microdisk laser. ly2 The device makes use of optical modes at the edge of a thin semiconductor dielectric disk which is 2-10 pm in di...
Abstract Whispering-gallery mode (WGM) cavities formed by dielectric structures have attracted intensive interest in various fields. The high-quality factor and smaller volume associated with the optical modes inspired experiments nonlinear optics, nanophotonics, quantum information science. Moreover, they are also used biosensors other significant applications. To further reduce material loss ...
We report the experimental demonstration of an optically pumped silver-nanopan plasmonic laser with a subwavelength mode volume of 0.56(lambda/2n)(3). The lasing mode is clearly identified as a whispering-gallery plasmonic mode confined at the bottom of the silver nanopan from measurements of the spectrum, mode image, and polarization state, as well as agreement with numerical simulations. In a...
An exact solution for the problem of interaction between whispering gallery modes of spherical microresonators and a single dipole is presented. It is predicted that experimentally observed spectral doublets associated with this interaction are a part of a triplet whose third component has yet to be observed. It is also shown that the interaction between the dipole and nonresonant whispering ga...
