Summer School "Frontiers of Solid State Light Sources" - Sept. 2 - Sept. 3, 2018


The conference includes a two-day Summer School to be held from Sunday, September 2nd (all the day) to Monday, September 3rd (morning), 2018. PhD Students and Postdocs who have paid the conference fee are especially invited to attend the Summer School. They will receive free entrance to the Summer School. The same rule will be applied for the full paying conference participants. The lecture program will be presented by lecturers who are internationally renowned in their research subjects. It will give students a chance to get introduced into various laser related subjects, covering the basics up to the latest research results.

High-Q Microcavities for Gyroscopes and Soliton Microcombs
In the last 15 years there has been remarkable progress in boosting optical storage time in micro and millimeter-scale optical resonators. Chip-based devices attain Q factors of nearly 1 billion and micro-machined crystalline devices provide Qs exceeding 100 billion.  Extremely large resonant build-up effects are possible in these devices.  And these have created new perspectives for access to a wide range of nonlinear phenomena at very low power.  Whole new classes of chip-integrated devices have resulted, including stable optical soliton sources for frequency-comb generation and high-coherence Brillouin lasers for rotation measurement. This course will first review microresonator physics and examples of nonlinear optical phenomena accessible using these devices. Then, two major areas of research that apply nonlinear resonator physics will be discussed in detail.

In the first, the generation of highly coherent light in Brillouin microlaser systems will be examined. Beginning with fundamental limits to laser coherence caused by microwave-rate thermo-mechanical quanta, the demonstration of sub-Hertz Schawlow-Townes linewidths in chip-based Brillouin lasers is discussed.  Application of these systems for highly stable microwave generation and rotation sensing is then described.  In the second application area, the generation of microresonator optical solitons using the Kerr nonlinearity will be overviewed. Beginning with essential soliton physics, resonator design principles required to form stable solitons will be discussed. The formation of bi-soliton systems that result from Raman interaction with the solitons is also reviewed as well as the stability of the resulting frequency comb (`microcomb’). Finally, current efforts to miniaturize time standards and stable frequency sources for metrology and spectroscopy will be described. This will include developments towards a new generation of compact optical clocks and recent demonstrations of dual-comb spectroscopy systems using chip-based microcombs.

Attosecond Photonics: An Introduction
The course will focus on the basic ideas, methods and techniques developed over the last 15 years in the area of attosecond physics. Methods for the measurement of light waves and attosecond pulses, the synthesis of light fields with sub-cycle presicion, measurement  and understanding of attosecond phenomena in gasses and solids. An important part of the course will focus on the new possibilities  that emerge by driving electrons in solids with intense and fast laser fields. How  can we now make solid-state photonic sources of attosecond extreme ultraviolet radiation. We will discuss also how strong optical field driving of electrons in bulk solids allow the establishment of new microscopies  with sub-angstrom resolution.

Giant Micro-photonics for Tiny Integrated Power Lasers
This course will discuss the impact and principle of Giant Micro-photonics based on micro-domain structure and boundary controlled materials for creation of new functions for tiny integrated power lasers, such as the transparent polycrystalline ceramics and periodically poled ferro-electric devices. The advanced engineered compact solid-state lasers and nonlinear optics are reliable, efficient and multi-functional light sources. Moreover, their micro domain causes a new interaction for coherent radiation. This effect should be enhanced by a micro cavity or a periodic structure. These micro and/or microchip lasers attained by using advanced ceramics can provide extreme performances as a new generation of solid-state lasers. The high-brightness nature of these downsized lasers has allowed the ubiquitous power lasers for new innovation and science.

Label-Free Optical Imaging
This course discusses the principles behind optical microscopes that are capable of generating images with molecular selectivity without the use of fluorescent labels. An emphasis will be placed on the underlying light-matter interactions that allow molecular selective imaging in a non-invasive and non-perturbing fashion. Nonlinear optical techniques are an important class of label-free imaging techniques, and the basics and capabilities of these techniques will be discussed, along with examples of their application in biology and the biomedical sciences. Overall, this course illuminates these selected topics from a physics and engineering point of view.
Objectives: By the end of this course the students will:
•    Understand the importance and advantages of label-free imaging in the biomedical sciences.
•    Have a basic understanding of the light-matter interactions that allow label-free contrast.
•    Be familiar with criteria that govern light source selection and microscope design.
•    Be acquainted with nonlinear optical methods and how these technologies have advanced biomedical imaging.
