Technical Paper Round-up: August 8


New technical papers added to Semiconductor Engineering’s library this week. [table id=44 /] Semiconductor Engineering is in the process of building this library of research papers. Please send suggestions (via comments section below) for what else you’d like us to incorporate. If you have research papers you are trying to promote, we will review them to see if they are a good fit for... » read more

Ultra-Fast Photonic Computing Using Polarization


New technical paper titled "Polarization-selective reconfigurability in hybridized-active-dielectric nanowires" was recently published by researchers at University of Oxford and University of Exeter.  The paper demonstrates "the ability to use polarization as a parameter to selectively modulate the conductance of individual nanowires within a multi-nanowire system. By using polarization as the... » read more

Photonic computing with polarization Researchers at the University of Oxford and University of Exeter developed a method that uses the polarization of light to maximize information storage density and computing performance using nanowires. The researchers note that different polarizations of light do not interact with each other, allowing each to be used as an independent information channe... » read more

Optical oscilloscope Researchers from the University of Central Florida developed an optical oscilloscope to measure the electric field of light. The high speed at which light oscillates has made reading its electric field challenging, with current instruments able to resolve an average signal associated with a pulse of light rather than individual peaks and valleys within the pulse. “... » read more

Optical memory Researchers at the University of Oxford, University of Exeter, and University of Münster propose an all-optical memory cell that can store more optical data, 5 bits, in a smaller space than was previously possible on-chip. The optical memory cell uses light to encode information in the phase change material Ge2Sb2Te5. A laser causes the material to change between ordered and... » read more

Polariton graphs In a development that a team of researchers from the UK and Russia say could eventually surpass the capabilities of even the most powerful supercomputers, a type of ‘magic dust’ — which combines light and matter — can be used to solve complex problems. Hailing from the University of Cambridge, University of Southampton and Cardiff University in the UK and the Skolk... » read more

Chaos-based IC Researchers at North Carolina State University and the College of Wooster developed a three transistor nonlinear, chaos-based integrated circuit combining digital and analog components, which they hope can improve computational power by enabling processing of a larger number of inputs. In chaos-based, nonlinear circuits, one circuit can perform multiple computations instead... » read more

Power/Performance Bits: Sept. 22


Photonic memories A team of researchers from Oxford University, the University of Münster, the Karlsruhe Institute of Technology, and the University of Exeter produced the first all-photonic nonvolatile memory chip. The new device uses the phase-change material Ge2Sb2Te5 (GST), used in rewritable CDs and DVDs, to store data. This material can be made to assume an amorphous state, like glass... » read more
