Self-heating leads to a temperature rise of the laser diode and limits the output power and efficiency due to increased loss and decreased differential gain. To control device self-heating, it is required to design the laser structure with a low optical loss, while the heat flux must spread out of the device efficiently. In this study, a new asymmetric waveguide design is proposed and th...

After more than 40 years of evolution, testing has become a very diverse field as broad as electronics itself. Consequently, the test community today must cope with an enormous spectrum of difficult problems ranging from, for instance, logic synthesis for testability to noise and heat dissipation problems in extremely high performance (in reality analog) pin electronics. This level of difficult...

3-D IC technologies have recently drawn great interest due to their potential performance improvement, power consumption reduction and heterogeneous components integration. One of the largest challenges in 3-D IC design is heat dissipation. In this paper we propose a thermal-aware physical design process for 3-D ICs, including floorplanning (3DFP-T), placement (T3Place) and routing (TMARS). Tem...

HEAT DISSIPATION BOUNDS FOR NANOCOMPUTING: METHODOLOGY AND APPLICATIONS

The second law of thermodynamics prohibits spontaneous heat from a cold to hot body. However, it has been theoretically and experimentally shown that energy can flow body if the bodies are initially correlated. We investigated \emph{anomalous exchange} between dissipation-less quantum systems entangled. Then, we extended this model include dissipation demonstrating heat} Based on these models, ...

challenges facing many diverse industries, including microelectronics, transportation, solid-state lighting, and manufacturing. Technological developments such as microelectronic devices with smaller (sub-100 nm) features and faster (multi-gigahertz) operating speeds, higher-power engines, and brighter optical devices are driving increased thermal loads, requiring advances in cooling. The conve...

We study the effect of dissipation on the infinite randomness fixed point and the Griffiths–McCoy singularities of random transverse Ising systems in chains, ladders and in two dimensions. A strong disorder renormalization group scheme is presented that allows the computation of the finite temperature behavior of the magnetic susceptibility and the spin specific heat. In the case of ohmic dissi...
