Space-division multiplexing optical coherence tomography.
High speed, high resolution and high sensitivity are desirable for optical coherence tomography (OCT). Here, we demonstrate a space-division multiplexing (SDM) technology that translates long coherence length of a commercially available wavelength tunable laser into high OCT imaging speed. We achieved an effective 800,000 A-scans/s imaging speed using a 100,000 Hz tunable vertical cavity surfac...
متن کاملOptical orthogonal division multiplexing for long haul optical communications: A review of the first five years
Optical OFDM was proposed for dispersion compensation in long-haul optical communications systems in 2006 in two forms, one using direct-detection and the other using coherent detection. Since then there has been extensive innovation towards developing intermediate forms of optical OFDM that are more suited to specific applications. This review paper presents our view on the developments in opt...
متن کاملOrbital Angular Momentum-based Space Division Multiplexing for High-capacity Underwater Optical Communications
To increase system capacity of underwater optical communications, we employ the spatial domain to simultaneously transmit multiple orthogonal spatial beams, each carrying an independent data channel. In this paper, we show up to a 40-Gbit/s link by multiplexing and transmitting four green orbital angular momentum (OAM) beams through a single aperture. Moreover, we investigate the degrading effe...
متن کاملWavelength and Space Code Division Multiplexing in Optical Tomography
Optical Tomography aims at reconstructing one or more spatially variable coefficients in a volume from measurements of propagation of near infrared light fluxes at its surface. The propagation of near infrared photons in biological media has a diffusive nature, as photons are absorbed and massively scattered by tissues, and coefficients are reconstructed by post-processing algorithms. Time reso...
متن کاملSpace-division multiplexing: the next frontier in optical communication
Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity for optical communication. It is applicable for optical communication in both free space and guided waves. This paper focuses on SDM for fiber-optic communication using few-mode fibers or multimode fibers, in particular on the critical challenge of mode crosstalk. Multiple-input–multipleoutput (MIMO) equa...
