Actuation of Micro-Optomechanical Systems Via Cavity-Enhanced Optical Dipole Forces [PDF]

, 2007
We demonstrate a new type of optomechanical system employing a movable, micron-scale waveguide evanescently-coupled to a high-Q optical microresonator. Micron-scale displacements of the waveguide are observed for milliwatt(mW)-level optical input powers.

A case of successful laser coagulation in pediatric ophthalmology: a patient with the optic disc pit complicated by serous neuroepithelial detachment

Journal of Ophthalmology, 2016
Introduction. Optic disk pit has been considered as coloboma located, as a rule, near temporal part of the optic disc. Central serous retinal detachment develops in 50 % of patients.

Single-pixel imaging of the retina through scattering media [PDF]

, 2019
Imaging the retina of cataractous patients is useful to detect pathologies before the cataract surgery is performed. However, for conventional ophthalmoscopes, opacifications convert the lens into a scattering medium that may greatly deteriorate the ...

Thermal noise of whispering gallery resonators

, 2012
By direct application of the fluctuation-dissipation theorem, we numerically calculate the fundamental dimensional fluctuations of crystalline CaF2 whispering gallery resonators in the case of structural damping, and the limit that this noise imposes on ...
