No data traffic without Axetris microlenses
Axetris has been providing microlenses to the communication industry for more than 15 years and microlenses are omnipresent in telecom and datacom solutions such as wavelength selective switches, optical transceivers for data centers and long-haul coherent communications components. It all started with Passive Optical Network (PON) components for the megabit telecommunication era. Today, Axetris contributes cost-attractive microlenses to the advance of Gigabit internet age, where hyperscale data centers and service providers require more efficient, economical and faster solutions. Customized silicon and fused silica microlenses and microlens arrays Axetris microlenses are made of high quality optical materials like silicon and fused silica, which have optimal properties for optical communication solutions.
We produce microlenses with customized lens designs and also auxiliary features, such as fiducials and metal- or solder pads. Microlens chips are provided in the form of single-lenses or 1- and 2-dimenional lens arrays, which cover single- and multi- channel coupling schemes.
size, down to a few hundred microns with thicknesses down to of 100 µm, which enables compact packaging and miniaturized optical setups. Microlenses are manufactured by well-established micro- machining processes, the same techniques used in silicon photonics fabrication: photo- lithography, thermal reflow, and plasma etching. These micro-
machining techniques guarantee sub-nanometer surface roughness, high-precision pitch accuracy for microlens arrays, and good control of the lens shape for customized lens designs. The wafer-level processes allow scalability to high volume production and eventually cost-attractive solutions.

Cable connectors for the modern world – 3M™ Expanded Beam Optical Interconnect
3M has reimagined fibre optic connector technology to deliver connectors that are designed to reduce the need for maintenance, cleaning and human interaction, yet offer exceptional performance. Conventional cable connectors rely on physical contact and can be vulnerable to transmission interruptions from debris like dust or skin oil. 3M’s design has expanded the light beam and changed the light angle in the optical connector, revolutionizing how cables connect and perform – while reducing risk. The 3M™ Expanded Beam Optical Connector System is a multi-fibre connector system based on a new expanded beam ferrule technology. Conventional multi-fibre connectors make use of physical contact between fibres. The 3M™ Expanded Beam Optical Ferrule expands the beam between connectors, reducing the connector’s
sensitivity to dust and the need for frequent cleaning. The connector system supports low insertion loss and high return loss connectivity with a common technology for single mode or multimode fibres. Critical mating alignment is controlled by the expanded beam ferrule without the use of metal guide pins protruding from the end of the connector. The system utilizes a hermaphroditic connector geometry with an LC-connector style latch to engage bulkhead adapters. 3M™ Expanded Beam Optical Connectors are designed to deliver: l Stable performance which supports multi- link deployment l Low insertion loss and reflectivity in both single mode and multimode fibre l Reduced sensitivity to dust l Repeatable mating and re-mating performance
l Simple connector designs with low part count l Configurable and scalable connector designs (12 fibres to 144 fibres) l Interconnect for rack or infrastructure applications With decades of experience in interconnect solutions, 3M is ready to apply the best of 3M Science and collaborate to develop the technologies that will propel the future of our data driven world.
