作为华中科技大学六十周年校庆的系列活动之一，学校邀请了一批具有不同学术背景的海内外青年科学家来我校就若干前沿科学主题展开交流与探讨。经过学院邀请，许艳菲博士等五位光电信息领域的青年学者将于10月8日下午4点30到我院南五楼二楼220会议室进行学术交流，欢迎各位老师和同学踊跃参加。
附五位青年学者研究方向：
1、许艳菲博士，Marie Curie Fellow （欧盟玛丽居里学者/博士后），主要研究石墨烯的可控功能化、光电性质研究及其在非线性光学、光检测器、光伏电池、透明电 极、场效应晶体管器件领域中的应用。
2、孙海定博士，波士顿大学PhD Candidate & Research Assistant，主要研究领域：My research interests cover both the theoretical and experimental aspects of the physics of Group III-Nitrides(AlInGaN) based optoelectronics materials and devices & the physics of quantum well structures, and nanostructure and plasmonics. The experimental aspects include the material epitaxy with molecular beam epitaxy(MBE) & device fabrications of III-Nitride semiconductor optoelectronics devices. The device applications addressed in my research include semiconductor light emitting diodes (LEDs) and semiconductor lasers for non-line of sight communications and biomedical applications.
3、张川博士，明尼苏达大学PhD Candidate，主要研究方向包括：Efficient Hardware Design for Polar Decoder（With thorough investigation of the dependent flow graph for polar decoders, VLSI-DSP techniques are employed to achieve the best compromise within decoder latency, throughput, and hardware consumption）；Architecture for Reed-Solomon Based Non-Binary LDPC Decoders（By exploring shifting properties of Reed-Solomon based non-binary LDPC codes, layer decoding at different levels has been employed to increase both design efficiency and flexibility）
4、刘小赤博士，法国FEMTO-ST Ph.D student, 主要研究Coherent Population Trapping Atomic Clock. The objective of my actual research is to develop a Bi-Frequency Bi-Polarization (BiFBiP) laser system to detect a high contrast of a Coherent Population Trapping (CPT) resonance. This technique can improve the short term frequency stability of a CPT atomic clock. In the classical CPT clock, the contrast of a CPT resonance is about 1%. Inspired by the different optimized CPT clocks, I have proposed a BiFBiP system and some advanced phase noise reduction techniques to apply in a CPT atomic clock. By using such a system and phase noise reduction technique, CPT resonance with contrast up to 50% is observed.
5、方瀛博士，美国莱斯大学博士后，主要研究成果包括：1）通过飞秒激光的灼烧效应，定量描述了表面激子导致的表面电磁场场强的极端分布，和其对表面增强拉曼光谱的增强因子的影响。揭示了表面增强拉曼光谱实际主要是由少数在热点地区的分子所贡献的，并对没有经过特殊优化的一般样品上的热点地区的增强因子进行了测量；2）利用单粒子光谱测量，深入研究了金纳米粒子单光子光致发光的机理，定量研究了纳米棒的长径比对这一过程的量子产率的影响。通过和荧光分子的类比，提出了解释这一现象的模型；3）采用分秒激光红外泵浦，拉曼探测的手段，定量研究了几种液相小分子的振动能量衰减过程，以及溶质的热效应。
