Download or read book A Near Field Scanning Optical Microscopy Investigation of Photonic Structures written by Aditi Sharma and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Near field scanning optical microscopy (NSOM) is used to study two different photonic structures. The two structures were a photonic crystal sample and a selectively oxidized vertical cavity surface emitting laser (VCSEL) where spectroscopic NSOM is utilized to investigate the transverse mode structure. NSOM is a unique tool for studying these samples as the optical intensity and the spectroscopic signatures of these samples are characterized with sub-wavelength spatial resolution. The photonic crystal sample is a two-dimensional slab waveguide with a silicon nitride core and silicon dioxide cladding. The photonic lattice comprises of a triangular lattice of 20 rows of air pores, with air pore diameter of 146 nm and lattice constant of 260 nm, etched into the top cladding and the core. Due to the periodic modulation of the dielectric constant in the air pore lattice, a photonic band gap is expected for this lattice in the visible wavelength regime. NSOM was used to characterize the optical intensity distribution within the photonic lattice region at a wavelength of 633 nm. In addition, Bragg reflections were observed from the lattice region and the angular dependence on the angle of incidence of the input beam was recorded and compared to a point scatterer model. The transmission across the lattice was also calculated, in both 2D and 3D, using a program based on a finite difference time domain method and compared to experimental data. The VCSEL sample is a selectively oxidized 850 nm VCSEL having a square aperture of side length 10 micron. An NSOM coupled to a spectrometer is used to obtain both spatially and spectrally resolved images of the VCSEL's emission. The spatially resolved intensity distributions for eight of the lowest order transverse modes of the VCSEL were obtained, in the near field and far field, at three different currents i.e. around threshold (3.3 mA) and above threshold (at 5 mA and 7.5 mA). The modes are identified as being Hermite-Gaussian and their spatial orientations show how they utilize the available gain of the cavity effectively. Two-dimensional maps of the total integrated intensity of the spectra reveal an inhomogeneous gain distribution. The wavelengths of the transverse modes are observed to increase with increasing current at an average rate of 0.145 nm/mA. Calculations showed that a temperature-induced change in refractive index of the cavity was the dominant contributing factor towards this red shift.

This book was released on 2006-10-24 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Making a clear distinction is made between nano- and micro-mechanical testing for physical reasons, this monograph describes the basics and applications of the supermicroscopies AFM and SNOM, and of the nanomechanical testing on rough and technical natural surfaces in the submicron range down to a lateral resolution of a few nm. New or improved instrumentation, new physical laws and unforeseen new applications in all branches of natural sciences (around physics, chemistry, mineralogy, materials science, biology and medicine) and nanotechnology are covered as well as the sources for pitfalls and errors. It outlines the handling of natural and technical samples in relation to those of flat standard samples and emphasizes new special features. Pitfalls and sources of errors are clearly demonstrated as well as their efficient remedy when going from molecularly flat to rough surfaces. The academic or industrial scientist learns how to apply the principles for tackling their scientific or manufacturing tasks that include roughness far away from standard samples.
Download or read book Sub Wavelength Probing and Modification of Complex Photonic Structures written by Silvia Vignolini and published by Firenze University Press. This book was released on 2010 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis consists in the study and modification of complex photonic nano-structures. Nowadays, propagation of light in such materials is a rich and fascinating area of research, both for its fundamental implications and for its practical technological impact. To deeply investigate light propagation inside these structures a high spatial resolution technique is required, especially because intriguing effects often occur on length scales comparable with the diffraction-limit or involve coupling phenomena on this length scale. For this reason in this thesis a Scanning Near-Field Optical Microscope represents one the most straightforward tool both to study and locally modify complex photonic nano-structures from perfect periodic to completely random ones.
Download or read book Near Field Optics written by Dieter W. Pohl and published by Springer Science & Business Media. This book was released on 1993 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scanning near-field optical microscopy (SNOM, also known as NSOM) is a new local probe technique with a resolving power of 10--50 nm. Not being limited by diffraction, near-field optics (NFO) opens new perspectives for optical characterization and the understanding of optical phenomena, in particular in biology, microelectronics and materials science. SNOM, after first demonstrations in '83/'84, has undergone a rapid development in the past two to four years. The increased interest has been largely stimulated by the wealth of optical properties that can be investigated and the growing importance of characterization on the nanometer scale in general. Examples include the use of fluorescence, birefrigence and plasmon effects for applications in particular in biology, microelectronics and materials science, to name just a few. This volume emerged from the first international meeting devoted exclusively to NFO, and comprises a complete survey of the 1992 activities in the field, in particular the variety of instrumental techniques that are currently being explored, the demonstration of the imaging capabilities as well as theoretical interpretations - a highly nontrivial task. The comprehensive collection of papers devoted to these and related subjects make the book a valuable tool for anybody interested in near-field optics.
Download or read book Advances in Near Field Optics written by Reuven Gordon and published by Springer Nature. This book was released on 2023-09-15 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together tutorial-style expository chapters on both foundational material and current research areas in near-field optics. The starting point for the book was the Summer School at the 16th International Conference on Near-Field Optics, Nanophotonics and Related Techniques (2022), with each Summer School short course represented by a chapter, along with an additional specially selected chapter on a complementary topic. Together, the chapters within present a modern perspective of the area of near-field optics, focusing on recent theoretical approaches, but also capturing the evolution of the field. Each chapter is written by an internationally-recognized expert and provides a tutorial on a different aspects of the theory and analytical methods for near-field optics, nanophotonics, and plasmonics. While the material will be accessible at the graduate level, it will also provide a useful reference for established researchers in near-field optics and scientists in nearby fields.
