Telecentric Optics for Focus Analysis

Magnification variations due to changes in focus setting pose problems for vision techniques, such as, depth from focus and defocus. The magnification of a conventional lens can be made invariant to defocus by simply adding an aperture at an analytically derived location. The resulting optical configuration is called “telecentric.” It is shown that most commercially available lenses can be turn...

High-Density Integrated Optics

This paper presents two-dimensional (2-D) finite difference time domain (FDTD) simulations of low-loss rightangle waveguide bends, T-junctions and crossings, based on high index-contrast waveguides. Such structures are essential for the dense integration of optical components. Excellent performance characteristics are obtained by designing the waveguide intersection regions as low-Q resonant ca...

QuantuM Optics correlations on a chip

cavity quantum electrodynamics describes the behaviour of a quantum emitter inside an optical cavity, and is one of the few realizable experimental systems in which the coherent interaction between the emitter and the cavity mode can exceed dissipative and dephasing processes. Recent advances in this field include the observation of vacuum Rabi splitting1–3, interference4, upconversion5 and the...
