教學與課程

自2007年以來，共開設本科教學基礎類課程三門，分別是《數字電路》、《數字系統設計I》、《固體物理與半導體物理》。開課以來，幽默的教學方式、循序漸進的教學理念、獨樹一幟的教學方法，頗受廣大學生喜愛。多年來，課程評價及課堂效果都非常理想。

每年指導5名本科生進行畢業設計，從2007年開始至今，已指導本科畢業設計38人，其中4人獲得“浙江大學本科生百篇優秀論文獎”的榮譽。

研究與成果

1. Nowadays, Single nanoparticle sizing and counting are essential for a broad range of applications. According to the practically sizing and counting difficulties, we proposed a new on-chip method and model based on a microring resonator device which solved the previous problems. Our work presents a new method for rapid and accurate counting and sizing of nanoparticles ranging from a few hundred nanometers to sub-10 nm. In the mean time, our method also affords to count the quantity of single nanoparticle. Based on the theoretical method and theory, we cooperate withUniv.ofMichiganresearch group, and initialed the measurement setup and sensor device. Some results have been published on Optics Express in 2013.

Attached figures are about the device structure and some results.

2. Propose an effective and innovative analysis model of photonic devices such as ring resonators, AWG, etc., based on Optical Low Coherence Interferometry (OLCI). Based on the universality of model, we construct the complete experimental platform of OLCI with significant improvement on accuracy of OLCI by initiatively incorporating polarization control and phase locking into the interference structure. The merits of the proposed analysis model for photonics devices have been proved via experiments that it could extract physical parameters of complicated integrated optics device with good accuracy, overcoming some limitations of previous OLCI analysis methods. This breakthrough has paved the way for further study of using low coherence interferometry to analyze more categories of objects. The results have been published on Journal of Lightwave Technology in 2012.

3. Cubic boron nitride (cBN) is currently attracting considerableinterest for applications in the fields of high-temperature and highpowerelectronic devices because of its excellent chemical stability,high thermal conductivity, wide bandgap with both n- and p-typedopability and a large breakdown electric field. Applying the first pricile method and Micro-fabrication we obtain some devices which could detect deep UV light. this could be used for solving the problem of 'Sun blind'. we granted by NSFC and published 3 SCI papers by now.
