Recently, we have seen rapid progress in the area of photonics and photonic circuits to meet the ever increasing demand for bandwidth and higher communication speeds. The key technology that will enable rapid progress to be achieved is the development and improvement of photonic integrated circuits (PIC). As is the case in electronics, silicon will most likely be the material of choice for the fabrication of PICs because it has a high transparency in the near infrared optical spectrum. Siliconbased photonics has additional advantages because the existing silicon-processing infrastructure can be used and there is considerable knowledge already available in the silicon microelectronics industry. The goal is to eventually achieve the monolithic integration of photonic devices and electronic devices on a single silicon microchip.

Ee Jin Teo

Ee Jin Teo received a first class honours BSc. and Ph.D degree in Physics at the National University of Singapore in 1998 and 2002 respectively. In 2003 she received the Singapore Millennium fellowship and in 2007 the Lee Kuan Yew fellowship, to further her postdoctoral research at the Centre for Ion Beam Applications, National University of Singapore. Her work on “Multicolor photoluminescence from porous silicon using focused high energy helium ions” was featured on the inside front cover of Advanced Materials and has won her first prize in the “Science as Art” competition at the 2007 Materials Research Society meeting, and Silver prize in the “Images of Science” competition at the 2007 Science Month organized by Singapore Science Centre. Her work on “Writing Structures in Silicon" was highlighted in the Research News in Materials Today. Her current research includes using ion beams to fabricate silicon waveguides with low loss for integrated photonics applications.
