Chun-ta Wang received his Ph.D. degree from Department of Photonics, National Sun Yat-sen University (NSYSU), Taiwan, in 2012.

After graduation, he worked as a postdoctoral fellow at NSYSU for three years, and was in charge of silicon photonics fabrication in National Nano Device Laboratory, Hsinchu, Taiwan.

In 2015, he successfully received a 3-years project (PI) from Ministry of Science and Technology (MOST).

During the period of this project, he went to Ghent University in Belgium and Hong Kong University of Science and Technology in Hong Kong as a visiting scholar.

In 2018, he started to join the department of Photonics as a faculty member.

His research interests are mainly related to liquid crystal optics and silicon photonics in both fundamental studies and device development.

He also received a project from Young Scholar Fellowship Program, MOST, Taiwan, entitled“Heterogeneous integration of silicon photonic devices.”

 

  Our research group has interests in the fields of silicon photonics, liquid crystal optics, and heterogeneous integration of electro-optic materials into silicon photonics. At the early stage, we focus mainly on the combination of liquid crystals (LCs) and passive silicon photonic device.

 

  Silicon photonics is a revolutionary technology which uses silicon as an optical medium. It has high-bandwidth and long-distance transmission characteristics and offers the potential of realizing low-cost and highly integration by using standard CMOS fabrication techniques. The ideal silicon photonics platform should base on silicon waveguide foundation but not limit to only using silicon as the photonic material, in particular as active function material. Due to its intrinsic material limitations, the silicon cannot provide adequate functionality to meet the needs of all components, especially in some specific modulators which need a large optical tuning ability. The weak electro-optical effect of silicon limits its application in active element.

 

  In recent years, many studies combine passive silicon photonics devices with liquid crystals to fabricate various active silicon photonics devices with multi-functionality due to liquid crystals’ large birefringence, low power consumption, and versatile driving methods. What all this means is that liquid crystal material is a promising candidate for development of active silicon photonics devices. Therefore, we develop and explore the integration of organic LCs into the silicon waveguide structure for realizing the multi-functional LC silicon photonic devices. Furthermore, other electro-optic materials, like PZT and high stress materials, will be studied.
