Technology demonstrator for micro-lens arrays facilitates testing in your own optical systems
Precision collimator arrays for optical switching architectures are increasingly common, for example in telecommunications and hyperscale data-center networks. In order to give developers the opportunity to sound-out the potential of this technology, INGENERIC now presents a micro-lens array (MLA) as a demonstrator, which interested parties can request from the company.
In long-haul and metro networks, „all-optical“ switching and routing functions offer considerable advantages. Compared with optical-electrical-optical (OEO) switching, they enable significantly higher Internet bandwidths and shorter latency times.
One example is the wavelength-sensitive switch, which handles the multiplexing, switching and re-multiplexing in third-generation Reconfigurable Optical Add-Drop Multiplexing (ROADM) systems. The basic building blocks of these switches are usually one-dimensional micro-lens arrays that couple the light signals into the output fiber arrays.
Helping developers to test this technology in their own optical systems under practical conditions, INGENERIC has developed a one-dimensional (1D, 1×16) micro-lens array available on request from INGENERIC.
Dr. Stefan Hambücker, Managing Director of INGENERIC GmbH, explains why he is making the demonstrator available to a wide range of users: „While we develop many of our projects closely with customers – with the corresponding confidentiality clauses in place – we are for the first time introducing the MLA demonstrator, a micro-lens array that developers can very easily integrate into their optical systems. It is easy to order from our website with just a few clicks.“
In addition to the demonstrator, interested parties can request the white paper „Perfecting the art of fiber collimation with micro-lens arrays“ with extensive technical data and the results from detailed measurements on the INGENRIC website ( https://fiber-collimator-array.ingeneric.com/), or get in touch with the INGENERIC specialists online.
The MLA demonstrator is a one-dimensional, plano-convex 1×16 MLA that INGENERIC produces using precision glass molding. It couples light signals in free space or with an intervening glass spacer in fiber arrays. Reference marks minimize the time required for alignment and pre-adjustment in optical systems.
From demonstrator to series
Users who are convinced of the benefits can contact INGENERIC and discuss their individual requirements with the engineering team. This can include, for example, the design of transition zones or the selection of the most suitable glass. Immediately after order placement, INGENRIC begins with the production of the molds and the first prototypes, right up to serial production.
The advantages of precision glass molding for micro-lens arrays
-Significant cost savings through high mold reproducibility
-Low beam-direction errors and high coupling efficiency due to extremely small pitch errors
-High focal-length uniformity due to small radius errors
-Low optical losses due to minimal mold defects and low surface roughness
-Minimal crosstalk of the signals due to negligible dead zones between the lenses
Typical applications for fiber collimator arrays
Optical switching in free space:
– Coupling of signals in single- and multimode fibers used at wavelengths commonly used in telecommunications
– Switching in data centers and telecommunications networks, for example with wavelength-selective switches (WSS)
Optical free-space communication systems:
– Coupling of light signals between optical fiber arrays and other components in free space
Reconfigurable optical add-drop multiplexing (ROADM) systems:
– Optical components for signal multiplexing/demultiplexing
– Optical transmission in long-distance, metro and access networks with mesh topographies
