Tech Talk "Integrated Optics in Silicon" by Dr. Steven Spector, MIT Lincoln Lab

Wednesday, April 24 from 6:00 pm to 7:30 pm in Lavery Hall 330

Integrated Optics in Silicon
Dr. Steven J. Spector1, Dr. Michael W. Geis2, and Dr. Theodore M. Lyszczarz3
MIT Lincoln Laboratory

Silicon is an attractive platform for the integration of optical components because of the mature infrastructure dedicated to the fabrication of silicon microelectronic devices. Furthermore, the silicon optical components can be readily integrated with transistors to form complex signal processing systems. At the wavelengths most relevant for optical communication (near 1550 nm), silicon has a high index and low inherent loss, making it an ideal material for compact devices. However, such compact devices also have large scattering loss. In addition, the electro-optic effects are weak in silicon, making it difficult to realize active components. This seminar will describe techniques for fabricating low-loss silicon waveguides, optical filters, low-power silicon PIN diode optical modulators, and high-performance silicon photodiodes using a complementary metal-oxide semiconductor (CMOS) integrated circuit process. The photodiodes exploit ion-implantation damage to create midgap states that enhance sensitivity at the 1550 nm wavelength. These components are being developed for a high-speed optical sampling system that will be used to implement an analog-to-digital converter.

altEngineers must be proficient, professionally astute, and clearly aware of their responsibility to society. Student Professional Awareness Conference (S-PAC, pronounced "ess-pak") explores the subjects that affect engineers' careers, regardless of how well engineers prepare themselves technically.  

This year, the Virginia Tech IEEE is hosting this event on Saturday, March 30th from 2 to 8 PM at the Owens Banquet Hall.  The topics to be discussed include entrepreneurship, company management and operation, patents and intellectual property, and the importance of graduate school. There will be $600 in raffle prizes and a three-course meal will be served.

Hello everyone,
I wanted to take the time to thank all those who have signed up for the IEEE S-PAC event. We have reached our maximum limit of participants for this event, thus the survey is now closed. All the registered attendees will receive an email containing the schedule of the event and further instructions.
Once again, thank you for making this event such a success.

Arash Majdi
Chair-Virginia Tech IEEE
