In this paper, we present here a miniaturized wavelength tunable laser with an extended feedback model for potential all optical network applications. The feedback model has been developed to study the wavelength tuning characteristics of the micromachined tunable lasers in the weak and medium feedback limits. The miniaturized tunable laser, having a size of 2 mm 1.5 mm 1 mm, is an integrated F...

In this paper, an inverse S-shaped slotted ground structure (S-SGS) is proposed and analyzed. The S-SGS generates dual attenuation poles that can be easily controlled by its structure parameters. The equivalent circuit of the S-SGS consists of lumped elements that can be extracted from the measured S parameters. Moreover, several S-SGS cells are applied to form a miniaturized lowpass filter (LP...

Gene manipulation in mice is now a routine approach to the investigation of disease pathophysiology. Examination of cardiovascular physiology in mice have required the development of miniaturized hemodynamic monitoring systems, or essentially mouse “cath labs,” in which catheters and guidewires are manipulated in mouse vessels often ,1 mm in size. Cardiovascular integrative physiology has becom...

Swarm Microrobotics aims to apply Swarm Intelligence algorithms and strategies to a large number of fabricated miniaturized autonomous or semi-autonomous agents, allowing collective, decentralized and self-organizing behaviors of the robots. The ability to establish basic information networking is fundamental in such swarm systems, where inter-robot communication is the base of emergent behavio...

The rapid emergence of nanoelectronics, with the consequent rise in transistor density and switching speed, has led to a steep increase in chip heat flux and growing concern over the emergence of onchip “hot spots” in microprocessors, along with such high flux regions in power electronic chips and LED’s. Miniaturized thermoelectric coolers (μ-TEC’s) are a most promising cooling technique for th...

Lab-on-a-chip devices for cell culturing are becoming imperative in order to satisfy the needs for point-of-care or decentralized laboratory testing. Towards that goal we have developed miniaturized membrane based cell culture chambers for use within the field of chromosome analysis. The same principle was applied for the development of a miniaturized cell migration device. Flow and concentrati...

The exploitation of enzymes for biotransformation reactions for the production of new and safer drug intermediates has been the focus of much research. While a number of enzymes are commercially available, their use in an industrial setting is often limited to reactions that are cost-effective and they are rarely investigated further. However, the development of miniaturized flow reactor techno...
