We introduce a novel polarizing beam splitter that uses the anisotropic spectral reflectivity (ASR) characteristic of a high-spatial-frequency multilayer binary grating. Such ASR effects allow us to design an optical element that is transparent for TM polarization and reflective for TE polarization. For normally incident light our element acts as a polarization-selective mirror. The properties ...

Optimal optical parameters of the beam splitter that is used in the division-of-amplitude photopolarimeter are determined. These are (1) 50%-50% split ratio of the all-dielectric beam splitter, (2) differential phase shifts in reflection and transmission delta(r) and delta(t) that differ by +/- pi/2, and (3) ellipsometric parameters (psi(r), psi(t)) = (27.368 degrees, 62.632 degrees) or (62.632...

In-plane All-photonic Transduction Method For Silicon Photonic Microcantilever Array Sensor Jong Wook Noh Department of Electrical and Computer Engineering Doctor of Philosophy We have invented an in-plane all-photonic transduction method for photonic microcantilever arrays that is scalable to large arrays for sensing applications in both bioand nanotechnology. Our photonic transduction method ...

A time-dependent dielectric cmedium is used to model a time-varying beam-splitter inside a cavity. The time-varying boundary conditions smoothly evolve from a highly transmitting to a highly reflecting beam-splitter. These approximately correspond to a transformation from a single cavity to a pair of cavities. Quantum field-theoretic calculations show that such a smooth change yields non-singul...

We have measured the conductance and shot noise of superconductor-normal metal S-N junctions between a niobium Nb film and a two-dimensional electron gas 2DEG , formed in an InAs-based semiconductor heterostructure. Adjacent to the junction, the 2DEG is shaped into a sub-micrometer beam splitter. The current shot noise measured through one arm of the beam splitter is found to be enhanced due to...

Scaling network intrusion detection to high network speeds can be achieved using multiple sensors operating in parallel coupled with a suitable load balancing traffic splitter. This paper examines a splitter architecture that incorporates two methods for improving system performance: the first is the use of early filtering where a portion of the packets is processed on the splitter instead of t...

In this paper, we suggest a novel system that is capable of measuring absolute distances with an uncertainty of one micrometer, or better, over a distance of up to 20 meters. This system consists of a Michelson interferometer, a tunable external cavity diode laser, a wavelength meter, a digital camera and a computer. The Michelson interferometer contains a reference arm mirror, a target arm mir...
