Faculty of Science P1701 PHYSICS - APPLIED PHYSICS Application of atomic force microscopy (AFM) in metrology (Dr. Roman Kubínek Department of Experimental Physics Today many technological applications, such as integrated circuits, diffractive optical elements and micromechanical devices, required measurements on small dimensions with an accuracy better than a few nm. Scanning probe microscopes (SPM) provide high resolution, three-dimensional data and are therefore very useful for measurements of micro- and nanostructured objects. The AFM technique works without any surface treatment even on nonconducting surfaces and is therefore well suited for measurements on all kinds of materials. Obligatory courses (examinations): Modern microscopic methods and their use in surface study (Dr. R. Kubínek) Modern microscopic techniques can be categorized into three groups: with fixed beam, scanned beam and scanned probe techniques. Use of techniques with fixed beam - Transmission Electron Microscopy (TEM) for surface analysis and analysis of nanopowder. The use of techniques with scanned beam (such as Scanning Electron Microscopy (SEM) or Scanning Transmission Electron Microscopy (STEM)) for 3D characterization of surface. The applications of Scanning Tunneling Microscopy (STM), the use of Atomic Force Microscopy (AFM), Near-field Scanning Optical Microscopy (NSOM), and related SPM methods.

The course is part of the optical science and engineering program at the New Jersey Institute of Technology, in Newark. It’s the bandwidth, stupid! That’s the most concise explanation of the explosive growth in interest in optical communications. This year’s Optical Fiber Communications conference drew a record 17,300 people, an astounding 70% increase over an already robust attendance last year. The number of exhibitors at the meeting, which was held in Baltimore in March, was up by 25%. More than 3400 jobs were posted for consideration by a record 300 job seekers—11 jobs per seeker. Similarly, the Photonics West conference, held in San Jose in January, drew a record attendance of 12,141, surpassing the previous year’s attendance by nearly a thousand.

Abstracts of Invited Lectures From Micromaser to Microlaser . O. BENSON, H. Walther, Sektion Physik der Universitat Munchen and Max-Planck-Institut fur Quantenoptik, Federal Republic of Germany - - - In the lectures the work on the on-atom-maser or micromaser is reviewed. This maser system is the most fundamental where a single atom interacts with a single mode of a cavity. With this setup, the generation process of non-classical light and other quantum phenomena can be investigated in detail. Furthermore, a brief review of the microlaser work will be given where the phenomena of cavity quantum electrodynamics lead to a very low threshold of the laser system. The situation has drastically changed in the last ten years after it became possible to excite large populations of highly excited atomic states characterized by a high principal quantum number n of the valence electron. These states are generally called Rydberg states, since their energy levels can be described by the simple Rydberg formula. Such excited atoms are very suitable for observing quantum effects in radiation-atom coupling for three reasons. First, the states are very strongly coupled to the radiation field (the induced transition rates between neighboring levels scale as n4); second, transitions are in the millimeter wave region so that low-order mode cavities can be made large enough to allow rather long interaction times; finally, Rydberg states have relatively long lifetimes with respect to spontaneous decay.

Supervisor: Prof Gerard Milburn. Already allocated. Full-field Fourier-domain optical coherence tomography (3F-OCT) Supervisor: Dr Andre Zvyagin It is not trivial to visualize internal structures of biological tissue using light.  Why not? – Because tissue is turbid.  Illumination of tissue with light produces a lot of scattered photons, which should be trashed, giving way to registration of a few information-bearing photons.  Optical coherence tomography (OCT), an optical analogue of ultrasound, is, therefore, so efficient to “cut through turbidity”.  OCT imaging of the human eye, skin and internal body tissues is impressive, and, yet, leaves an ample room for frame rate and sensitivity improvement.  Our recent innovation in the field, 3F-OCT, may offer this improvement. In 3F-OCT, a set of two-dimensional frames is recorded at discrete wavenumbers of the light source.  The resultant 3D-data cube contains comprehensive information on the 3D morphological layout of the sample that can be reconstructed in software.  The following three projects will assist in the realization of this technique:

Johannes Kepler is famous for discovering the laws of planetary motion, but he is less well known for writing what may have been the first science-fiction story to involve space travel. During his observations, the German astronomer noticed that tails of comets always point away from the Sun, which suggested that the Sun was exerting a sort of radiant pressure. This led him in 1609 - the year in which he published the first of his laws - to propose sailing from the Earth to the Moon on light itself. Of course, that was and still is the stuff of science fiction, but 400 years later Kepler's initial ideas about moving matter with light are very much a reality. While it may not be the most practical way of moving matter at the macroscopic scale, there is intense interest in optical manipulation and assembly at the microscopic scale, not least from biological researchers. Light can move matter because photons carry momentum: a photon of wavelength
