物理学哲学博士-非线性光学和光子学

研究主题包括非线性光-质相互作用，从而可以控制光，四波混合，相位共轭和波长转换。我们开发用于二阶和三阶非线性光学的材料，尤其是有机分子组件，并且通常研究光子学和光电子学的材料和效应。示例包括玻璃中的单晶，光子晶体，多孔和其他特种纤维，波导，谐振布里渊散射和用于准相位匹配的铁电畴图案。光子学在生物系统，近场光学和热辐射中的应用也有大量工作。博士学位课程包括一组核心课程，其中包括一些高级研究生课程，这些课程提供了广泛的物理学背景。从长远来看，与学生的研究领域以及博士学位论文的研究相关的专业课程很重要。在其他机
Research topics include nonlinear light-matter interaction that enables the control of light with light, four-wave mixing, phase conjugation, and wavelength conversion. We develop materials for second- and third-order nonlinear optics in particular organic molecular assemblies, and in general study materials and effects for photonics and optoelectronics. Examples include single crystals in glass, photonic crystals, holey and other specialty fibers, waveguides, resonant Brillouin scattering, and ferroelectric domain patterning for quasi phase matching. There is also considerable work on applications of photonics to biological systems, near-field optics, and thermal radiation.The Ph D program includes a set of core courses, including some at the advanced graduate level that provide the broad background in physics that is so important in the long run, specialized courses relevant to the research area of the student, and the research for the Ph D dissertation. Students entering with graduate level work at other institutions may include relevant courses taken at the other institutions in their proposal for candidacy, which includes all their course preparation as well as the research proposal for the dissertation. The Department of Physics at Lehigh University offers programs leading to the B.A. in astronomy, the B.S. in astrophysics, and to the B.A., B.S., M.S., and Ph.D. degrees in physics, as well as a summer research program for undergraduates. Research areas include astronomy and astrophysics, atomic, molecular, and optical physics, biophysics, computational physics, condensed-matter physics, general relativity, cosmology, and string theory, high-energy and accelerator physics, nano science, non-linear optics and photonics, plasma physics, soft-condensed matter and complex fluids, and statistical physics.
