Free-Space Optical Interconnects

SPIE Proceedings, 1989
A simple and efficient optical interconnection consisting of only a laser, two lenses, and a detector has been used to connect two high-speed digital circuits separated by over 24 cm. No external laser driver, detector preamplifier, or other interface circuitry was required. The interconnection operates at data rates of 400 Mb/s.

Free-space optical collinear crossover interconnects

Applied Optics, 1991
Two new optical free-space collinear cross-over interconnect schemes are suggested. The first optical implementation uses mirrors and beam splitters, while the second uses a Fresnel zone plate and lens combination. Some proof-of-principle experimental results are also presented.

Diffractive optics applied to free-space optical interconnects

Applied Optics, 1994
The optimum design of free-space optical interconnection systems utilizing diffractive optics is determined from a practical engineering standpoint for systems ranging from space invariant to fully space variant. System volume is calculated in terms of parameters such as the f-number of the diffractive lens, the wavelength of light, and also the total ...

Telecentric Optics for Free-Space Optical Link

2008 16th IEEE Symposium on High Performance Interconnects, 2008
We 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.

Optical interference on free-space optical transceivers

Frontiers in Optics, 2003
We investigate the effects of optical interference on the performance of free-space optical (FSO) network links. Experiments indicate that interfering laser pulses of varying peak power, wavelength, and repetition rate incident upon FSO transceivers can produce up to a 90% reduction of average network throughput.

Miniaturization of free space optical systems

Applied Optics, 2010
Coherent 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 ...

Space-time optical merons in free space

CLEO 2025
We present the first optical meron wave packet with a non-trivial spin structure mapped onto a 3D surface in momentum-energy space, demonstrating a propagation-invariant localized topological structure with dynamically tunable propagation characteristics and spatio-temporal evolution.
