Optical and Wireless Convergence for 5G Networks

Chapter 2 of this book summarises the work of the EU Seventh Framework project IPHOBAC-NG and is written by members of the project consortium, including aXenic’s Rob Walker and Steve Clements. This chapter describes the development of enabling technology leading to a successful field trial of an E-band (71-76GHz) hybrid fiber/wireless link, for which aXenic developed specialised Single Sideband (SSB) modulators antecedent to the current aXSD2050 IQ product.

UK Space Conference

aXenic Presents

 

In September 2019 aXenic presented at a Showcase event during the UK Space Conference held at the International Convention Centre in Newport, Wales. Rollo Hutson described an 8 week intern project he carried out at aXenic this summer investigating methods of extending the temperature range of aXenic’s Gallium Arsenide optical modulators. aXenic’s modulators already operate over a wide temperature range but some space applications require further extending the operating temperature to temperatures as low as -45C. 

Rollo’s work investigating methods to deliberately apply controlled stress to the chip to compensate the thermal stress added at low temperatures showed up very promising routes for further investigation.

Rollo joined 48 other interns at the showcase event who were funded by the UK Space agencies SPIN intern scheme, to share their experiences of working in the space sector.

aXenic and Optocap partner to develop Innovative Low Loss Microwave Interconnect for GaAs Modulators

aXenic Ltd and Optocap Ltd have won a competition for a 12-month collaborative research project awarded by Innovate UK under the recent Compound Semiconductor Applications fund.

The aim of the Innovate UK fund is to speed up the use of compound semiconductors in areas such as power electronics, RF/microwave, photonics and sensors.

In this project: the partners aim to develop a novel low loss microwave interconnect assembly process, so as much of the intrinsic compound semiconductor chip performance can be achieved in the packaged module as possible. The new assembly process is expected to be applicable to a wide range of compound semiconductor devices and not just the high-speed photonic modulators based on Gallium Arsenide produced by aXenic.

Steve Clements, CEO of aXenic, commented “the new assembly process will allow us to realise optical modulators with reliable broadband performance above 50GHz, which compares to constraints of around 40GHz with conventional processes”. Such high performance, high reliability optical modulators are required for demanding applications in satellite communications and in aerospace markets where photonic systems are prized for their high bandwidth, small size and lower weight than conventional electronics.

aXenic have extensive experience in GaAs optical modulators which they have developed over many years for application in fibre optical telecommunication systems. aXenic currently offer a range of optical modulators for digital communications and RF over fibre.

Optocap Limited, owned by the Alter Technology Group TUV Nord S.A.U., is a technology oriented company active in the field of optoelectronics & microelectronics package design and assembly services. Optocap offer a full design and assembly of custom Photonic products and is experienced in harsh environment applications, specifically the Space sector. Optocap has 34 staff all based at the Livingston facility in the UK.

Press Release Sept/2015

aXenic Acquires High Speed Optical Modulator Business

Sedgefield, County Durham, United Kingdom. aXenic today announced that it has acquired Finisar UK Ltd and its Optical Modulator business for an undisclosed sum from its parent company Finisar Germany, which is part of the Finisar Corporation. aXenic, whose shareholders include the Management and Employees of Finisar UK, plans to address wider markets than the telecom business which was the focus of its activity as part of Finisar.

With its largely UK based supply chain, aXenic offers Gallium Arsenide (GaAs) based modulators for telecom markets >100G and high bandwidth, high frequency and high linearity products aimed at 40GHz and above. It will continue to develop its business with support of European collaborative projects which are aimed in particular at the high frequency and analogue business markets. The experience and capabilities of the business go back over 20 years with background in product offerings in both telecom and analogue markets and delivery of both GaAs and Indium Phosphide (InP) based products.

“We are really excited about the prospects of the new operating business with the opportunity to broaden our market access and interests for the developing business in highest speed and high bandwidth modulator products” said Steve Clements the CEO of aXenic. “We look forward to engaging with our customers in this area to offer high performance yet cost effective functions in a growing business.”

About aXenic:

aXenic’s technology was originally developed as part of the semiconductor business within Filtronic and was acquired by u2t Photonics in 2009. Last year u2t was itself acquired by Finisar Corporation. aXenic’s products and expertise covers semiconductor modulator design, optical and high speed test and optical packaging. It uses a subcontract route to product build and its product platform is supported by its established and developing patent portfolio.
