Trapping Light With Mirrors
نویسنده
چکیده
We show that, given finitely many line-segment mirrors in the plane, that do not touch, and an arbitrary point source of light, if all angles made by lines parallel to mirrors are rational multiples of π, then all but countably many emitted light beams escape. This result is shown to imply that, for a given point source of light, a randomly chosen configuration of finitely many nontouching line-segment mirrors has a nonzero probability of letting at least one light beam escape.

Narrowing light rays with mirrors
Pach raised the question of whether a match lit in a nite forest of disjoint circular mirror trees necessarily sends light to innnity CFG90]. In other words, can one trap light rays from a point source with such mirrors? This remains an unsolved problem. We pose related mirror trapping questions. Can one trap light with arbitrarily curved mirrors? Here the answer is yes. Can one trap light with...
متن کاملبررسی اثر پوشش نانودی‌اکسیدتیتانیوم بر خاصیت خود تمیز شوندگی و ضد باکتریایی آینه‌های دندانپزشکی
Objective: Surface coating of dental mirrors using nanotechnology has been done to render them self-cleaning properties. Nano-scaled titanium dioxide particles (TiO2)show antimicrobial properties when exposed to ultra-violet (UV) light. The aim of this study was to evaluate the effect of surface coating of dental mirrors with nano titanium dioxide on their self-cleaning (from dentists’ perspe...
متن کاملImproving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires
In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...
متن کاملTechnologies for trapped-ion quantum information systems
Scaling up from prototype systems to dense arrays of ions on chip, or vast networks of ions connected by photonic channels, will require developing entirely new technologies that combine miniaturized ion trapping systems with devices to capture, transmit, and detect light,while refining how ions are confined and controlled.Building a cohesive ion system fromsuch diverse parts involvesmany chall...
متن کاملSelf-organization of frozen light in near-zero-index media with cubic nonlinearity
Optical beams are generally unbound in bulk media, and propagate with a velocity approximately amounting to the speed of light in free-space. Guidance and full spatial confinement of light are usually achieved by means of waveguides, mirrors, resonators, and photonic crystals. Here we theoretically demonstrate that nonlinear self-organization can be exploited to freeze optical beams in bulk nea...
