IMPRS get-together

 

Place: optics seminar room 01.779 at the physics department building in Staudtstraße 7

Organisation: Robert Buschlinger (MPL & FAU / Leuchs Division)

Talk: Semiconductor Nanowire Photonics

Speaker: Robert Röder (Friedrich-Schiller-University Jena)

Abstract:

The forthcoming limitations of conventional electronic integrated circuits promote reinforced work in nanophotonics to overcome the drawbacks of electrical interconnects by on-chip optical data processing and transmission. Semiconductor nanowires are promising building blocks for on-chip optoelectronic components, as they are functional and connecting units in both electronics and photonics: They offer highly localized light emission and mark, due to efficient waveguiding, the lower physical size limit of multimode photonic laser systems. Thus, semiconductor nanowires are ideal nanoscale light sources for optical data transmission and processing in a spectral range that is typically determined either by the direct band gap of the material or by optical impurities. In this talk I will cover mainly 2 topics: The green CdS nanowire laser and different approaches to modify its lasing properties. I’m furthermore going to sketch a route to a ZnO nanowire impurity waveguide and resonator.

IMPRS get-together

 

Place: MPL (Large seminar room *435)

Organisation: Sebastian Bauerschmidt (MPL / Russell Division)

Talk: Whispering gallery mode resonators: linear and non-linear optics from the visible to THz

Speaker: Harald Schwefel (MPL / WhiGaMoR group)

Abstract:

Even the best non-linear optical materials require intense optical fields to utilize their non-linearity. Monolithic optical resonators are the ideal platform to provide these high intensities as well as long interaction regions, with moderate input powers. Some of the best optical resonators with a small footprint are whispering gallery mode (WGM) resonators. Their principle is based on continued total internal reflection at the interface of a convex dielectric. In this talk I will provide the basics of optical resonators with emphasis resonators of the WGM type and give an overview of recent applications of such resonators.

MPL Distinguished Lecturer Series

 

Speaker:

Prof. Shanhui Fan (Stanford University, Ginzton Laboratory, Stanford, USA)

Place:

MPL / large seminar room (*435)

Abstract:

Electromagnetic interaction, as one of the most fundamental interactions of the universe, lies at the heart of much of modern science and engineering. Novel mechanisms to control electromagnetic interaction, as evidenced by the recent developments of a wide variety of nanophotonic structures, therefore have broad implications for both fundamental and applied research. In this talk, we present two separate examples of some of our recent works in seeking to create novel electromagnetic interactions, and to exploit these interactions for new applications. We will show that one can achieve an effective gauge field for photons, which leads to a rich set of new non-reciprocal physics effects, as well as a very promising avenue towards on-chip non-magnetic linear optical isolator. We will also discuss some of our recent works in using nanophotonic structures to control heat flow, in both the near and the far fields.

Distinguished Lecturer Series

 

Speaker:

Prof. Elisabeth Giacobino (CNRS, École normale supérieure, Université Pierre et Marie Curie, Paris, France)

Place:

MPL / large seminar room (*435)

 

Abstract:

In a semiconductor system, optical excitations can create excitons, which are bound electron-hole pairs. In semiconductor nanostructures the excitonic energy levels are quantized, leading to a strong size dependence of their optical properties and allowing engineering of classical and non-classical light generation. Two cases will be described, one involving quantum wells with 1D quantization, the other one involving quantum dots, with 3D quantization.
When a quantum well is placed in a high finesse microcavity, the strong coupling regime between 2D excitons and light is reached, forming exciton-photon mixed quasi-particles called polaritons. Polaritons combine the coherent properties of photons with the highly interacting features of electronic states. These properties have allowed us to demonstrate nonlinear and quantum optical effects in the microcavity emission, as well as quantum fluid properties in the propagation of polaritons in the system. 
Quantum optical properties of quantum dots, or semiconductor nanocrystals, made of a few thousand atoms will also be described. Here, the strong confinement of electron-hole pairs leads to very interesting properties such as photon antibunching, opening the way to on-demand single photons sources at room temperature.
