Technology Overview

The Company has developed a fully integrated platform of optical and photonic capabilities combining a range of 3D waveguides, precise alignment features for fiber interconnects and micro-optic components. The Company’s technology uses laser based manufacturing to directly write optical waveguide circuits and micromachined structures within a block of glass. Integrating these micro-structures provides new levels of fiber coupling and significant relaxation of optical transceiver design constraints in terms of layout, assembly and packaging. Additionally, laser-based scribing simplifies manufacturing to a two-step process that delivers low signal loss, high density and scalable products. These compact glass-based 3D photonic integrated circuits are produced using the Company’s in-house fast wafer scale processing capabilities.

Introduction to Space Division Multiplexing

In long range telecommunications, this demand is currently met by Wavelength-division multiplexing (WDM) and coherent detection techniques, to increase network bandwidth on a singlemode fiber (SMF). To date, this has enabled optical transport networks to increase network bandwidth and meet demand. However, the capability of such approaches to continue increasing the available bandwidth will soon diminish. In an impending capacity ‘crunch’ caused by the Shannon nonlinear limit an alternative approach to data multiplexing will be required. Moreover, the cost of increasing spectral efficiency up to the Shannon limit will become prohibitively expensive.

The use of multiple parallel optical paths in the form of space division multiplexing/spatial division multiplexing (SDM) is seen as the way forward. SDM is implemented through the use of multiple fiber arrays, multicore fibers (MCF), multimode fibers (MMF) and few mode fibers (FMF) to increase the available bandwidth.

Parallel data transmission through spatial multiplexing also has significant applications in short range communication, where the component simplicity and reduced cabling costs associated with SDM can offer significant advantages in data-centre interconnects. Our waveguide technology is an innovative and disruptive technology that reduces physical footprint and enables the transfer of volume amounts of data across both long and short distances.

For SDM solutions connecting single mode fibers (SMF) to multicore fibers (MCF) or few mode fiber (FMF) has never been more simple using Optoscribe products.
