In digital holographic microscopy (DHM) achieving phase sensitivity is signifcant, which plays a major role in deciding the accuracy of the system. Our study elucidates the achievement of axial sub-nanometer precision with improvement in net phase sensitivity by instantaneous use of phase reference and temporal averaging techniques in DHM. To enhance the spatial resolution we implemented a synthetic aperture (SA) DHM system. The use of spectrum normalization method in SA-DHM system has helped to increase the spatial resolution and the phase sensitivity of the system. We also demonstrated the 3D imaging method based on sectional imaging technique to measure the refractive index variation between the spliced end of single mode fber and the polarization maintaining fber with digital holographic microscopy and tomography system (DHMT).© Anita Publications.

In real-time Optical Pattern Recognition (OPR), Fringe-adjusted Joint Transform Correlation (FJTC) has shown very promising performance compared to alternate JTCs. This paper provides a systematic review of the recent advances in the FJTC based OPR algorithms, including the classical FJTC, Phase-encoded FJTC (PFJTC), Shifted Phased-encoded FJTC (SPFJTC), and Logarithmic FJTC (LFJTC). We also evaluate their performance on the face recognition using three standard face recognition databases, namely the Yale face database, the extended Yale-Bdatabase and CMU-AMPdatabase. Test results show that the LFJTC provides superior performance compared to the state-of-the-art FJTC based OPR methods.

Hyperbolic metamaterials (HMMs) are metal-dielectric composite materials that exhibit hyperbolic dispersion for electromagnetic waves. The extreme anisotropy and broadband optical density of states associated with hyperbolic dispersion enable enhanced spontaneous emission rates and nonlinear processes, as well as guiding of light below the diffraction limit. While promising for next-generation nanophotonic devices and circuits, the behavior of passive HMMs are limited by fixed properties and high dissipation rates. Therefore, HMMs with active components for tunable properties and loss-compensation have become a subject of intense research. In this review, we investigate active and tunable HMM in the near-infrared frequency regime. We review HMMs based on indium gallium arsenide phosphide (InGaAsP) multiple quantum wells (MQW), a gain material commonly used in lasers for communication systems, as well as HMMs based on aluminum-doped zinc oxide (AZO), a transition conducting oxide with synthesis-dependent properties. We also offer an outlook on circuit-level applications of active, near-infrared HMM. © Anita Publications. All rights reserved.

1 Introduction
Photonics is the scientific and engineering discipline devoted to the generation, transmission, processing, and detection of light. Fueling photonics are fundamental questions rooted in human curiosity along with practical questions rooted in human wants and needs. Photonics combines classical electromagnetism and condensed matter physics, with engineering practices, enabling the global fiber-optic communication system, energy-efficient illumination, and devices for sensing disease and pollution. Increasingly, the interaction of light with materials at the nanoscale has become more accessible and better understood. Nanoscale photonics, or herein simply, nanophotonics, focuses on these interactions, and combines the tools of nanotechnology with the already interdisciplinary scope of photonics.
Moore’s Law  [1] describes the revolutionary process in which the characteristic length scale of transistors was reduced from over 10 μm to 5 nm, between the 1960s and today, resulting in the reduction of per-transistor price from 5 dollars to less than one billionth of one dollar  [2]. Guided by the International Technology Roadmap for Semiconductors, the information processing and storage capacity of human civilization has increased exponentially  [2,3]. Photonics undoubtedly helped enable the electronics revolution through photo-lithography machines with ever increasing resolution. However, because the ultimate speed limit of photons far exceeds that of electrons, there has also been a steady trend to reduce the characteristic length scale of photonic devices themselves  [4]. Traditionally, the dimensions of optical components, such as cavities and waveguides, have been limited to the order of the wavelength of operation. Nanophotonic devices have emerged, however, with sizes below the diffraction limit of light.

Digital micromirror device (DMD), a kind of widely-used spatial light modulator is applied in tunable fiber lasers as wavelength selector. Based on the two-dimensional diffraction theory, the diffraction of DMD and its effect on properties of fiber laser parameters are analyzed in detail. The theoretical results show that the diffraction efficiency is strongly dependent upon the angle of incident light and the pixel spacing of DMD. Compared with the other models of DMDs, the 0.55-inch DMD grating is an approximate blazed state in our configuration, which makes most of the diffracted radiation concentrated into one order. It is therefore a better choice to improve the stability and reliability of tunable fiber laser systems. © Anita Publications. All rights reserved.

Transport of intensity and phase during beam propagation

Department of Electro-Optics and Photonics, University of Dayton, Dayton, OH 45469, USA

Dedicated to Prof FTS Yu


Propagation of profiled beams are analyzed using the coupled equations involving the amplitude (or intensity) and phase which result from the underlying wave equation.  It is shown that the transport of intensity equation, which provides a convenient means of calculating the phase and is an alternative to conventional holography, is equivalent to one of these coupled equations, and is a restatement of the conservation of energy. Other applications of the equations describing the propagation of intensity and phase are also discussed. © Anita Publications. All rights reserved.

Frequency dependent thermo-optic coefficients of relaxor ferroelectric Pb1 – xBaxNb2O6, 1–x = 0.57 (PBN57) were measured at several optical wavelengths, 694nm, 633nm, 535nm, and 450nm. The thermo-optical coefficients are expressed in three terms describing relaxor-type diffusive phase transitions. The significance of the polarization term coming from the interaction among polar regions is discussed and confirmed, after comparing with the thermo-optic properties of PZN-0.12PT(0.88Pb(Zn1/3Nb2/3)O3-0.12PbTiO3) normal-like ferroelectric crystal. © Anita Publications.

In this paper, we present the implementation of a simple and low cost optical spectroscopic system based on the use of a common cell phone camera. It is shown how it can be useful for developing both qualitative spectra visualizations, to but also quantitative measurements. Therefore, it can be useful for application in demonstrations in science museums, as well as for introductory courses of Physics. In addition, it is also useful  to measure wavelengths in a very simple manner.We show results with different gas-discharge lamps, lasers, LEDs or filament bulbs. © Anita Publications.
