We present a photon splatting technique which reduces noise and blur in the rendering of caustics. Blurring of illumination edges is an inherent problem in photon splatting, as each photon is unaware of its neighbors when being splatted. This means that the splat size is usually based on heuristics rather than knowledge of the local flux density. We use photon differentials to determine the siz...

We have modified the existing convolution method of the Monte Carlo simulation for finite photon beams with both translational and rotational invariance. The modified convolution method was applied to simulate the optical fluence distribution in tissue in dark-field confocal photoacoustic microscopy. We studied the influence of the size of the dark field and the illumination incident angle on t...

We study a system made up of one or two two-level quantum emitters, coupled to single transverse mode closed waveguide, in which photon wavenumbers and frequencies are discretized, characterize the states excitation is steadily shared between field emitters. unearth finite-size effects field-emitter interactions identify family dressed bound that represent forerunners continuum limit an infinit...
