Overview of Ming C. Wu's short course: This short course will present a comprehensive overview of the Optical MEMS and bio-nano-photonics technologies. There is increasing interest in the development and application of Optical MEMS. In addition to the well-known digital micromirror device (DMD) for projection display, new displays based on interference modulation and micro shutter array are being developed for mobile devices. They are also increasingly used in telecommunications (2D and 3D switches, reconfigurable wavelength add-drop, tunable lasers/detectors) and imaging (micromirror scanners, adaptive optics, dynamic focus control). After an introduction to the fundamentals of free-space and guided-wave optics, we will describe the Optical MEMS devices for various applications in detail. In addition to free-space systems, planar lightwave circuits (PLC) and the emerging Si photonics platforms will be introduced. The latter enables the monolithic integration of electronic, photonic, and potentially MEMS circuits on a CMOS platform. Optofluidics is an emerging technology that combines microfluidic and optical circuits on the same substrate to synthesize new functionalities. Microfluidics provides a new mechanism to control light. For example, compact tunable lens (such as zoom lens) can be realized by changing the shape of microfludic lenses. Displays using electrophoresis (electronic paper) and electrowetting will be discussed. Conversely, light can be used to control or enhance microfluidic circuits. Optical trapping using laser tweezers and novel optoelectronic tweezers will be discussed. The last subject covers nanophotonics and its applications in bio and chemical sensing. The fundamentals of nanophotonics, including photonic crystals and high-Q resonators, near-field optics, plasmonics, and optical antennas, will be introduced. Finally, we will discuss their applications in bioanalysis systems. Surface plasmon resonance (SPR) is commonly used to detect antibody-antigen reactions, enzyme substrate reactions, and DNA hybridization at the sensor surface. Nanofabricated plasmonic structures offer higher sensitivity and spatial resolution. Surface-enhanced Raman spectroscopy (SERS) will be discussed. Outline:
