PLATON - 35N - III-V Nanophotonics

01.03.2009 - 28.02.2015
Forschungsförderungsprojekt
The main objective of this research project is the cavity design and fabrication of active elements like quantum cascade devices and development of the epitaxial growth - by integrating quantum dots - for opto-electronic device applications. The utilization of light for communication purposes and other functionalities still poses fundamental problems both in physics and device technology. In this project we investigate new concepts for the generation, manipulation and detection of light making use of photonic band gap (PBG) materials. Structures will be designed, simulated, optimized, manufactured (by epitaxy, wafer bonding and charged particle lithography and alternatively by nano-imprinting) and tested. We will also investigate alternative laser concepts and new effects taking advantage of the strong nonlinear coefficients of III-V materials and the high quality of photonic crystal resonators. Technological aspects will be developed in close collaboration/interaction with other RP¿s. In parallel we intend to investigate different methods to prepare a regular growth matrix serving as seeding structure for QD nucleation. A promising approach is the defined pre-patterning of the substrate in combination with self-assembly in the subsequent epitaxial growth process, namely:(i) holography, (ii) Electron Beam lithography (EBL), (iii) Gallium - focused ion beam lithography (FIB), (iv) Nano-imprint lithography (NIL), and, starting in the second year, (v) masked Ion Beam direct Structuring (ProFib). As a long term goal self assembled ordered quantum dots and quantum dot stacks will be embedded into optoelectronic devices. We intend to combine the results of both workpackages and realize high quality photonic structures, where the active material is based on transition within quantum dots. This approach has high potential to signifycantly improve the overall performance of existing intersubband devices like e.g. quantum cascade lasers.
