The talk will focus on Optical MEMS technology where the MEMS device is utilized for an Optical function. Optical MEMS is playing a critical role in many important areas such as Optical Networks, LIDAR, Virtual Reality, 3D Imaging, and various Biomedical applications. Devices that operate on the phase of an Optical beam require less movement and can be much faster. Examples of such devices include GLV (grating light valve), Diffractive MEMS, and Tunable Fabry Perot filters. Many applications are enabled by Micromirror devices that rotate in one or two axes. Different approaches are used depending on mirror size, speed, rotation angle, and whether used in a controlled or resonant mode. One or two dimensional arrays of mirrors are needed for some applications such as Optical Cross-connect Switches. The talk will also review design methodologies and process fabrication methods.


AG Microsystems (AGM was founded by Asif A. Godil, a visionary technical and business leader with a proven track record of bringing cutting edge technology to market to address real business needs. AGM is focused on Optical MEMS technology and in particular on MEMS Micromirrors. These are being used in Optical Networks and a host of other applications.

Prior to his work at AGM, Asif founded and built LIGHTCONNECT into a major supplier of MEMS-based fiber optic components and modules for the Telecom market. LIGHTCONNECT was successfully acquired by Neophotonics Corporation which is now part of Lumentum. In the Optical MEMS space, a highly significant development was the GLV (Grating Light Valve)-based scanned projection display, which Asif co-invented and developed at Silicon Light Machines. After Asif completed his Ph.D. in Electrical Engineering from Stanford University, Sony invited him to spend a couple of years as a Visiting Scientist at its Research Center in Tokyo, Japan.
