Free-space Optics for Communications at Sea
Optical Fiber Communication Conference (OFC) 2022, 2022We discuss our free-space-optical communication system, specifically exploring tradeoffs in pointing, acquisition, and tracking design and the use of retransmission to mitigate the impact of turbulence-induced fades.

Telecentric Optics for Free-Space Optical Link
2008 16th IEEE Symposium on High Performance Interconnects, 2008We describe a telecentric optical system for free-space multichannel optical interconnects. The targeted aggregate data rate is 240 Gb/s. We have a unique implementation of telecentric optics and achieved an optical link that is simple, robust and modular.

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

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.

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.

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 ...

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.

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 ...

On space-time coding for free-space optical systems
IEEE Transactions on Communications, 2010Atmospheric turbulence-induced fading is one of the main impairments affecting free-space optics (FSO) communications. In this paper, we consider FSO systems with intensity modulation and direct detection (IM/DD) and derive a closed- form expression for the asymptotic pairwise error probability of general FSO space-time codes (STCs) for two lasers and ...
