On the phase of plasmons excited by slits in a metal film
The excitation of surface plasmons by subwavelength slits in metal films is studied using a rigorous diffraction model. It is shown that the plasmon is launched by a slit in... -
Spontaneous pattern formation in a cavity with incoherent light
We present the first experimental observation of spontaneous pattern formation in a nonlinear optical cavity in which the circulating light is both spatially and temporally... -
Ultrasmall spot size scanning laser ophthalmoscopy
An ultrasmall spot size scanning laser ophthalmoscope has been developed that employs an annular aberration-corrected incident beam to increase the effective numerical aperture... -
Effects of light environment during growth on the expression of cone opsin ge...
Abstract Background The visual system is important for animals for mate choice, food acquisition, and predator avoidance. Animals possessing a visual system can sense particular... -
A live cell assay of GPCR coupling allows identification of optogenetic tools...
Abstract Background Animal opsins are light-sensitive G-protein-coupled receptors (GPCRs) that enable optogenetic control over the major heterotrimeric G-protein signaling... -
Ultrahigh speed 1050nm swept source / Fourier domain OCT retinal and anterior...
We demonstrate ultrahigh speed swept source/Fourier domain ophthalmic OCT imaging using a short cavity swept laser at 100,000 – 400,000 axial scan rates. Several design...
