Electronic and photonic integrated circuits use optics to overcome bottlenecks of microelectronics in bandwidth and power consumption. Silicon photonic devices such as optical modulators, filters, switches, and photodetectors have being developed for integration with electronics based on existing complementary metal-oxide-semiconductor (CMOS) circuits. An important building block of photonic devices is the optical ...

2008
This work presents the development of a platform technology for the rapid synthesis of a wide range of one-dimensional nanostructures using induction heating. The technique is fast, enabling the synthesis of nanostructures in as short as one minute, simple, clean, and scalable. The technique is also versatile, enabling the synthesis of nanostructures in bulk or locally on MEMS, and may open up a new class of rapid nanostructure synthesis....

Research in the micro- to nanoscale regimes is facilitated by technologies that enable the addressing of these tiny particles. In biological research, manipulation enables the study of single-cell behavior, as well as the sorting of specific target cells from a mixed population. In engineering applications, micro- and nanoparticles can be assembled to form electronic and optoelectronic devices. Several types of forces can be used to manipulate micro- and...

Since the invention of the laser, stimulated emission has been the de facto king of optical communication. Lasers can be directly modulated at rates as high as 50GHz, muchfaster than a typical solid statelight-emitting diode(LED)that is limited by spontaneous emission to <1GHz. Unfortunately, lasers have a severe scaling problem; they require large cavities operated at high power to achieve efficient...

The ability to manipulate biological cells and micrometer-scale particles plays an important role in many biological and colloidal science applications. However, conventional manipulation techniques, such as optical tweezers, electrokinetic forces (electrophoresis, dielectrophoresis (DEP), and traveling-wave dielectrophoresis), magnetic tweezers, acoustic traps, and hydrodynamic flows, cannot achieve high resolution and high...

2011
The design and fabrication of MEMS Inertial Sensors (both accelerometers and gyro-scopes) made of Aluminum Nitride (AlN) is described in this dissertation. The goal of this work is to design and fabricate inertial sensors based on c-axis oriented AlN polycrystalline thin films. AlN is a post-CMOS compatible piezoelectric material widely used for acoustic resonators, such Bulk Acoustic Wave (BAW) and Lamb Wave Resonators(LWR). In this work we develop the design techniques necessary to obtain inertial sensors...
