Free-space digital optical systems
Proceedings of the IEEE, 1994Within the past 15 years there has been significant progress in the development of two-dimensional arrays of optical and optoelectronic devices. This progress has, in turn, led to the construction of several free-space digital optical system demonstrators.

An integrated free space optical bus
Proceedings 1989 IEEE International Conference on Computer Design: VLSI in Computers and Processors, 2003As integrated circuit linewidths are reduced, single-chip system functionality and speed increase. Conventional electronic chip input/output does not follow this trend: bonding pad sizes and off chip capacitive loads remain essentially constant. Shortage of chip interconnect capability has become critical. Integrated free-space optical interconnect has

Optical circuitry for free-space interconnections
Applied Optics, 1990A means for losslessly implementing arbitrarily space-variant optical interconnections in free space without sacrificing optical space-bandwidth product or power is described. The technique uses space-variant mirrors and polarization beam splitters to separate and combine sets of device output spots, where a different interconnection operation is ...

Low-order adaptive optics for free-space optoelectronic interconnects
Applied Optics, 2000 The concept of adaptive optics for improving the cost-performance of free-space optoelectronic interconnects is discussed. Adaptive optics as a design option for optical interconnect systems is presented and discussed.

Free Space Optical Multicast Crossbar
Journal of Optical Communications and Networking, 2015Enabling multicast in optical networks requires the use of multicast-capable optical switches. In this paper, we propose a new class of multicast-capable free space optical (FSO) switches. Our design exploits nonmovable tri-state switching elements (T-SEs) that support signal splitting and switching simultaneously and seamlessly, and thus the separate ...

SPIE Proceedings, 1990
Free-space optical components and systems can be fabricated using planar techniques such as pattern generation using an electron-beam writer, photolithography, reactive ion etching and thin film deposition. This allows to integrate several optical components such as lenses and beamsplitters on one side of a single substrate [1]; see Fig. 1.

Free Space Passive Optical Network
2018This paper proposes free space passive optical network (FSPON) as a potential candidate of high data rate access network based on optical wireless transmission. FSPON could be considered for indoor as well as outdoor deployments. Pending the progress in FSO range, it is appropriate for short range communication network.

Free space optical wireless network
2011 13th International Conference on Transparent Optical Networks, 2011This talk explore an over the air optical wireless network and to create a network architecture for reliable high data rate free space optical networks that can interoperate with traditional wired and fiber networks. These networks will have significant impact for applications between ships, airborne vehicles, satellites and land-based cloud computing ...

Miniaturization of free space optical systems
Applied Optics, 2010Coherent illumination enables not only integrated optics, but also miniaturized free-space optics that takes advantage of the amplitude and phase control afforded by optical microelectromechanical systems (MEMS) and photonic crystals. These technologies also provide a practical and cost-effective means for integration and packaging of optical systems ...
