Free-space digital optics is a topic based on many disciplines: nonlinear optics, computer and switching network architectural design, semiconductor physics, mechanical design, and, of course, optical system design. Initial work in this area concentrated on the discovery and development of nonlinear optical effects with which to form optical switching ...

Free-space wavelength-multiplexed optical scanner
Applied Optics, 2001A wavelength-multiplexed optical scanning scheme is proposed for deflecting a free-space optical beam by selection of the wavelength of the light incident on a wavelength-dispersive optical element. With fast tunable lasers or optical filters, this scanner features microsecond domain scan setting speeds and large- diameter apertures of several ...

Optical interconnect using free space optics
Annual Meeting Optical Society of America, 1989Integrated free space optical interconnect has the potential to provide a large number of high speed connections between electronic integrated circuits. The overall optical arrangement is briefly described. We intend to use a single laser or a pair of lasers to power an interchip connection with several hundred communications channels.

200 G Outdoor Free-Space-Optics Link Using a Single-Photodiode Receiver
Journal of Lightwave Technology, 2020We experimentally evaluate the performance of Kramers–Kronig (KK) receivers for free-space optical transmission. We transmit a dual-carrier signal, each carrier modulated as a 25 Gbaud 16/32 quadrature-amplitude modulation (QAM) signal. This dual-carrier

A comprehensive road map of modern communication through free-space optics
Journal of optical communications, 2020Free-space optical communication (FSO) has emerged as an opportunity for future generation high-speed wireless communication, substituting its radio frequency (RF) counterpart. Considering few fiber optics limitations, FSO has been gaining its popularity

Simulating free-space optical computing architectures
Applied Optics, 1998Major issues in optoelectronic system design include timing, synchronization, and control. Designing free-space optical computing architectures is difficult because of the high degree of system complexity, parallelism, and concurrency in conjunction with the high cost and lack of availability of devices. Current simulation tools lack the expressiveness

Free-Space Optical Communications
Journal of Lightwave Technology, 2006With recent successes of laboratory, inatmosphere, and space demonstrations of free-space optical communications, there is no doubt that the technology is ready for operational deployment. While these successes have shown that there are no laws of physics against such systems, their estimated system costs are still much too high for serious ...
