The microstructures are used by our clients in an extensive range of applications. The choice of geometrical elements and structural features are just as diverse as the nature of the applications for which our clients require them.

Whether ceramic, glass or silicon: The components always meet even the most exacting demands in terms of form and surface quality.

We will be pleased to manufacture microstructures to meet your requirements, too.

Fiber arrays

Fiber arrays

Fiber arrays position glass fibers in relation to one another so accurately that they can be married to the optical chip with a minimum of work.

The drawbacks of silicon arrays - high costs, a lack of geometrical freedom due to process-related material characteristics and an increased risk of rejection at the array finishing stage as a result of the unfavorable combination of materials consisting of a silicon array, quartz glass fibers, cover element and polymer glue are completely eliminated by the arrays.

Characteristics and advantages

The arrays manufactured in accordance with the customized design are available in a wide range of materials (quartz glass, optical glass, ceramic) and guarantee complete macroscopic and microscopic geometrical freedom. Specific stopping surfaces to assist assembly can be fitted as can either V or U grooves, as required. The accuracy of the arrays is in the sub-micrometer range. Meticulous adjustment of a uniform material system to suit the jointed fiber array can thus ensure that the finishing operation conducted on the arrays, results in products of uniform quality.

Integrated fiber optics

Integrated fiber optics

High transmission rates in conjunction with the trend towards highly integrated systems, are resulting in a demand for efficient fiber-chip couplings.

As a result of meticulous structuring of a single-mode glass fiber end, for example, it has been possible to achieve lateral de-coupling of the light signals through the fiber cladding. Additionally, an additional micro-structure in the fiber cladding itself, substantially reduces the optical coupling paths between the fiber and the diode.

Characteristics and advantages

Replicable coupling efficiency levels exceeding 80 % have been recorded in function tests for elements of this type, manufactured to customer specifications. The work required of the customer in order to achieve active alignment in the assembly process has also been reduced considerably as a result of the manufacture-oriented definition of the geometrical elements. Cumulatively, users benefit from considerable cost advantages, a high level of transmission efficiency and a substantial degree of design freedom in terms of the integrated structure.

Monolithic prisms

Monolithic prisms

Micro-prisms are used as reflective or refractive elements in a number of applications. Many of our clients request the use of optical glass and extreme accuracy of the positioning of the prisms in relation to one another.

The monolithic prism arrays provide an efficient solution: Our arrays, which have very high surface quality, are oriented with the very highest levels of replicable precision in relation to one another, even when extremely complex arrangements of prismatic surfaces are required.

High-quality, optical glass is used.
