MEMS TECHNOLOGY DESIGN BY SERCALO

FIBER OPTIC MEMS

The acronym MEMS stands for Micro Electromechanical Systems. Fiber Optic MEMS, or micro electromechanical devices, are devices that allow a photonic signal, travelling at the speed of light through a fiber optic to be redirected, routed, or filtered.
MEMS are produced with high precision tools of the microelectronics industry, ideally suited for parallel manufacturing of 100s of chips on a single wafer.
The MEMS chips are the principal building block of Sercalo’s fiber optic products.
Fiber-Optic MEMS allow an extraordinary combination of optics, electronics, and micro mechanics, resulting in precise control of optical signals with the lowest losses.
The outstanding stability of Sercalo switches over time is critical in optical Test and Measurement to avoid test set up recalibration.

ON THE TECHNOLOGY

The Fiber Optic switch technology is based on the silicon technology that made the fame of the Silicon Valley in the late 60s. What is so complex about Fiber optic MEMS is that you must achieve mirrors of one micron wide and 100-micron high, remaining totally flat.

ON THE NEEDS OF THE INDUSTRY

The first need of the industry is to avoid and reduce the degradation of the signal to have the most minimal modal loss after each reflection in the mirror. This is a result Sercalo achieves in house thanks to unique production processes.
We have achieved such a level of quality and expertise through the 20 years focusing on this field and integrating vertically all the production processes.
There is a growing demand for fiber optical switches, and we observe an increased in interest in high port counts optical switching solutions. Sercalo currently offers fiber optic switches with ports count configurations of up to 16 inputs and 16 outputs, based on the highly reliable and proven Sercalo MEMS switches.

SERCALO & COMPETITIVENESS

Since 1999, Sercalo is a worldwide leading provider of fiber optic MEMS technology and products for telecommunications or test and measurement applications.
Sercalo is recognized for its High-Quality Swiss manufacturing and development.
It’s the combination of Swiss quality, with High productivity that enables us to make very Competitive products even in the light of what could produce other companies. For producing low volume Optical MEMS most of our competitors rely on an external foundry. We at Sercalo go the opposite road. To guarantee performance and quality, we do have our own foundry in house. Only this way we can have total control of our processes. Our location in Switzerland provides us with a unique culture and know-how in micro mechanics.
We are a very responsive engineering team, with a fast decision-making and development capability. Typically, we complete the proof of concept of a new product in less than 9 months and a time to market below 12 months.
