1 ATLAS Pixel Opto - Electronics
We have developed two radiation-hard ASICs for optical data transmission in the ATLAS pixel detector at the LHC at CERN: a driver chip for a Vertical Cavity Surface Emitting Laser (VCSEL) diode for 80 Mbit/s data transmission from the detector, and a Bi-Phase Mark decoder chip to recover the control data and 40 MHz clock received optically by a PIN diode. We have successfully implemented both A...
متن کاملOpto-Electronics Packaging And Failure Analysis Methodology
The demand for opto-electronics is increasing as we are nearing the future due to the need for high data rate, high bandwidth, lossless transmission and low electromagnetic interference sensitivity. The paper describes the present research carried on the mature laser technology i.e. GaAs, in order to improve its efficiency. The packaging principle used for receivers can be applied for the packa...
متن کاملFrugal Droplet Microfluidics Using Consumer Opto-Electronics
The maker movement has shown how off-the-shelf devices can be combined to perform operations that, until recently, required expensive specialized equipment. Applying this philosophy to microfluidic devices can play a fundamental role in disseminating these technologies outside specialist labs and into industrial use. Here we show how nanoliter droplets can be manipulated using a commercial DVD ...
متن کاملA Novel Opto-Electronics Interface-Circuit Design for Sensing Applications
A new and practical opto-electronic sensor interface is presented. It consists of a transmitter and a receiver for sensors measuring optical attenuation. Emphasis is given to commonlyneglected background-noise-interference and dynamic-rangelimitation problems. The design of the electronic circuitry allows sensors to operate in manufacturing environments. A modulated laser-diode, together with o...
متن کاملFluorene-based macromolecular nanostructures and nanomaterials for organic (opto)electronics.
Nanotechnology not only opens up the realm of nanoelectronics and nanophotonics, but also upgrades organic thin-film electronics and optoelectronics. In this review, we introduce polymer semiconductors and plastic electronics briefly, followed by various top-down and bottom-up nano approaches to organic electronics. Subsequently, we highlight the progress in polyfluorene-based nanoparticles and...
