Course Instructor

SC1230: Optical MEMS Engineering

This course provides an overview of the Optical MEMS technology from an engineering point of view. First, the course will explain the main features of the Optical MEMS market showing the different segments and the characteristics of each segment. Then, the course will give an overview of the main technologies in this domain showing the pros and cons of each technology from an industrial point of view and indicating some of their success stories. The attendees will then go through the details of the analysis and design of optical MEMS components. This includes the optical propagation through micro structures as well as the mechanical design of some common actuators (Comb drive actuator, thermal actuator, etc.) to be able to understand and appreciate the compatibility and contradictions faced when performing such designs. The course will be suitable for a beginner engineer who wants to penetrate the field of Optical MEMS as it allows him to ramp-up rapidly and jump into the initial design of a working optical MEMS component in a very short time.
