Simple analytical expression for crosstalk estimation in homogeneous trench-assisted multi-core fibers.
An analytical expression for the mode coupling coefficient in homogeneous trench-assisted multi-core fibers is derived, which has a simple relationship with the one in normal step-index structures. The amount of inter-core crosstalk reduction (in dB) with trench-assisted structures compared to the one with normal step-index structures can then be written by a simple expression. Comparison with ...
متن کاملSelective mode excitation and discrimination of four-core homogeneous coupled multi-core fiber.
Coupled modes of homogeneous coupled multi-core fiber are selectively excited and discriminated utilizing the difference of equivalent propagation angle. To quantatively evaluate the extinction ratio (selectivity) of adjacent modes, a new mode discrimination technique is developed by measuring the visibility of far-field patterns under small change of wavelength of the launching beam. The peak ...
متن کاملNovel multi-core fibers for mode division multiplexing: proposal and design principle
We propose a new type of optical fiber called homogeneous multi-core fiber (MCF) to drastically increase the transmission capacity of single fiber using the mode-division multiplexing. In this MCF, identical cores are closely arranged so that the cores are strongly coupled to each other to form coupled modes, each of which corresponds to a transmission channel. A novel mode multi/demultiplexer ...
متن کاملNeural networks within multi-core optic fibers
Hardware implementation of artificial neural networks facilitates real-time parallel processing of massive data sets. Optical neural networks offer low-volume 3D connectivity together with large bandwidth and minimal heat production in contrast to electronic implementation. Here, we present a conceptual design for in-fiber optical neural networks. Neurons and synapses are realized as individual...
متن کاملMimo Communications over Multi - Mode Optical Fibers
We consider multi-input multi-output (MIMO) communications over multimode fibers (MMFs). Current MMF standards, such as OM3 and OM4, use fibers with core radii of 50μm, allowing hundreds of modes to propagate. Unfortunately, due to physical and computational complexity limitations, we cannot couple and detect hundreds of data streams. In order to circumvent this issue, two solutions were presen...
