YOUR ULTRALOW NOISE SPECIALIST

Photonics - Electronics - GHz/THz

SILENTSYS pushes research and industry forward by making deep tech accessible in terms of cost, size and simplicity.

APPLICATIONS

Long optical fibers are widely used for temperature, strain, and acoustic sensing. This relies on Rayleigh, Brillouin, and Raman scattering. Such sensing systems are limited in distance and resolution partly due to the laser's coherence length. SILENTSYS provides highly coherent laser sources, dramatically enhancing optical sensing capabilities.

Lidar and Radar technologies are expanding rapidly, enabling greater distances and resolutions, for example, in wind speed monitoring. The oscillator source (laser or RF synthesizer) must exhibit minimal phase noise. SILENTSYS offers extremely low phase noise lasers, enabling tunable GHz/THz signal generation to boost Lidar and Radar.

Metrology, the science of precise measurements of physical quantities, increasingly relies on lasers and RF signals. The better the laser and RF quality, the more accurate the measurement. SILENTSYS provides low phase noise lasers and tunable low phase noise GHz/THz signals, advancing metrology with unmatched precision.

Quantum technologies are fundamentally transforming our world! These technologies explore matter at the microscopic scale (atoms, ions…). To interrogate, cool, and manipulate such particles, low phase noise and frequency-stable lasers are critical. SILENTSYS provides systems tailored for the rise of Quantum Technologies.

OUR EXPERTISE

SIGNAL noise & stability

SILENTSYS is among the few specialized companies worldwide with expertise in Frequency / Phase and Amplitude Noise, as well as Stability. We excel in all aspects of noise, stability, linewidth, and deviation related to Frequency, Phase, Intensity, Voltage, and more. When it comes to these domains, SILENTSYS is your trusted and unparalleled partner.

Signal Generation and Acquisition

The ability to acquire and generate low-noise, stable signals—such as voltages and currents—is a crucial aspect of electronic expertise for developing high-performance systems. With its rich history and continuous evolution, SILENTSYS stands as a key partner for providing dedicated assistance in this domain.

Thermal Stabilization

Temperature is one of the most significant physical factors contributing to noticeable mid- and long-term fluctuations in system performance. For example, it can affect the voltage of a power supply, the length of a material, or the output frequency of an oscillator. Achieving temperature stabilization is therefore essential to ensure high system stability. SILENTSYS possesses deep expertise in temperature stabilization and can maintain passive components with micro-Kelvin fluctuation levels for hours.

Vibration and Acoustic Isolation

In a controlled laboratory environment, the vibration and acoustic sensitivity of instruments like lasers and optical interferometers is less critical. These issues are typically addressed by using bulky and expensive optical tables mounted on pneumatic dampers. However, the situation is entirely different for embedded systems used in airplanes, boats, submarines, or ground vehicles. In such cases, minimizing vibrations and acoustic disturbances from noisy environments is crucial. Over the years, SILENTSYS has developed specialized expertise in this area, thanks in part to a strong collaboration with leading institutions in the field, including the University of Le Mans, ENSIM and LAUM.

COMPACT SYSTEMS

Cutting-edge scientific advancements are increasingly reaching higher Technology Readiness Levels (TRL), which necessitates significant system size reduction. This is a crucial step for transitioning newly developed technologies from the lab to real-world applications. SILENTSYS has successfully managed numerous industrial system development projects, gaining extensive expertise in miniaturizing laboratory technologies. Furthermore, SILENTSYS products are designed to be highly compact, providing optimal OEM solutions.

Fibered Photonic Scheme

Nowadays, photonic systems are predominantly quasi-fully fiber based. This offers numerous advantages such as reduced cost, simplified assembly, enhanced reliability, extended lifespan, and improved environmental robustness. SILENTSYS leverages extensive expertise in developing fiber-based photonic schemes, sourcing high-quality components, and performing precise packaging using dedicated industrial instruments.

Continuous and pulsed lasers

SILENTSYS can work both with continuous and pulsed (especially mode-locked) lasers, from 400nm to 2200nm.

Empowering the industrialization of your solutions with our expertise.
