Effects of a squeezed vacuum on absorptive optical bistabilityHaas, Steven Frederick, 1955- January 1988 (has links)
The effects of a squeezed vacuum on absorptive optical bistability (AOB) are calculated using the different relaxation rate approximation for in-quadrature and in-phase components of a two-level system developed by Gardiner. An expression for the complex absorption coefficient is developed, and the result applied to the AOB equation for the unidirectional ring cavity. We find a significant degradation of bistability for values of the in-quadrature decay constant less than or equal to approximately.5 of the in-phase decay constant. Effects of detuning and relative phase of the pump field to the squeezed vacuum field are also examined.

Trends in Vacuum Technology and Pneumatics in the Context of DigitalizationSchmalz, Kurt, Winter, Albrecht 03 May 2016 (has links) (PDF)
Digitalization is finding it’s way into production and machine-building. Autonomous, sefoptimizing and highly interconnected units will determine the functionality of machines and production facilities. Communication and automation layout will fundamentally change, data will be more and more the base for new business modells. Innovation is determining pneumatics and handling technology. The innovation topics performance improvement, modular and mechatronic design of systems, sustainability and efficiency are keeping pneumatics and vacuum technology on the pathway of success. But is the technology field also prepared for the tremendous challenges caused by the digitalization? This paper is focusing on the significance of digitalization for fluid technology, especially for pneumatics and vacuum technology.
The new concepts of digitalization and autonomization are based on the Internet of Things with open Communication of cyber-physical systems. These cyber-physical systems are able to react autonoumously. Cyber-physical systems can collect, interpret and analys data and transfer it into valuable information. Based on these data, cyberphysical systems will provide services to all participants of the smart factory. There will be a digital image inside the factory cloud, which is the base of new business models. Systems of pneumatics, vacuum technology and hydraulics will play a core role in this world. They are placed directly at the interface to the real technical process, they have direct contact with the workpieces, they are collecting multitude of sensor data and are evaulating it, they have functionality like Condition Monitoring and Energy Efficiency optimization on board and are able to communicate with the world of automation.
This paper will show, that the innovation trends of the last years are supporting the way towards digitalization and Industrial Internet of Things. There are already a lot of different approaches to establish vacuum and pneumatic systems as adequate elements of the digitalized world. It will also be shown, that fluid technology still is facing tremendous challenges It will be not sufficient to equip the systems with more functionality and better communication. It will be essential, that from the interpretation and correlation of data will be derived valuable services with real customer benefit. This should happen under control of the vendors of smart field devices in fluid technology. Then it will be possible to turn this new kind of value generation also into new business models.
