We report the experimental realization and characterization of one 60-mode copy and of two 30-mode copies of a dual-rail quantum-wire cluster state in the quantum optical frequency comb of a bimodally pumped optical parametric oscillator. This is the largest entangled system ever created whose subsystems are all available simultaneously. The entanglement proceeds from the coherent concatenation...

We present the design and performance of a highresolution, high charge sensitivity imaging camera system for the APS linac beam profile measurement. Electron beam distribution is converted to light intensity distribution using standard YAG or optical transition radiation (OTR) screens. Two CCD cameras share the light through a beam splitter, each with its own imaging optics. One camera is norma...

In this paper, a design for a 1 × 4 optical power splitter based on the multimode interference (MMI) coupler in a silicon (Si)-gallium nitride (GaN) slot waveguide structure is presented-to our knowledge, for the first time. Si and GaN were found as suitable materials for the slot waveguide structure. Numerical optimizations were carried out on the device parameters using the full vectorial-bea...

Unprecedented optical nonlinearities can be generated probabilistically in simple linear-optical networks conditioned on specific measurement outcomes. We describe a highly controllable quantum filter for photon number states, which takes advantage of such a measurement-induced amplitude nonlinearity. The basis for this filter is multiphoton nonclassical interference which we demonstrate for on...

Microoptical components, such as diffractive and refractive microlenses, micromirrors, beam splitter and beam combining have recently received considerable attention in the optics R&D centers and finally in the manufacturing community. This achievement is due to MEM technology that demonstrated major improvements in overall performance/cost of optical systems while offering the possibility of r...

Recently, there is great interest in monolithically integrated free-space micro-optics using micromachining techniques [ 11. Monolithic integration of the whole micro-optical system can drastically reduce its size, weight, and cost. In addition, the expensive packaging process of individual optical elements can also be eliminated. An example of the newly micromachined integrated micro-optical s...

The field of Augmented Reality (AR) is growing rapidly. Many of the options available now are very expensive, which is limiting to development of applications of the technology. We have designed and developed several opensource do-it-yourself (DIY) head-mounted displays for augmented reality (AR) that cost between $4 to $40. Optical design and simulations were completed using Zemax for a design...

We present the realization of a physical quantum random number generator based on the process of splitting a beam of photons on a beam splitter, a quantum mechanical source of true randomness. By utilizing either a beam splitter or a polarizing beam splitter, single photon detectors and high speed electronics the presented devices are capable of generating a binary random signal with an autocor...
