Proximion’s products and technologies enable critical functions in sectors where precision, reliability, and data integrity are essential. From high-speed telecommunications to structural health monitoring, our fiber optical solutions convert complex physical phenomena into measurable optical data — allowing operators, engineers, and researchers to see more, understand more, and achieve more.
Sectors
Optical Precision Across Every Industry
Past Projects
Our portfolio of past projects spans a wide range of applications built around three fundamental strengths:
- Dispersion control of light in optical fibers – mastering dispersion, delay, and interference.
- Accurate optical sensing – translating temperature, strain, and chemical changes into precise digital information.
- Photonic signal processing – filtering and dispersing optical signals for microwave applications with stability and scalability.
Telecommunications and Quantum Communications
In global fiber networks, Proximion’s dispersion management and optical monitoring solutions ensure signal integrity and channel performance over thousands of kilometres. Our dispersion compensation and emulation modules are key components in dense wavelength division multiplexing (DWDM) legacy networks and coherent transmission system development.
As communication security evolves, Proximion’s chirped FBG technology extend quantum key distribution (QKD) networks and secure optical reach with stabilized photon transmission in quantum networks — bridging classical fiber systems with the quantum future.

Industrial and Manufacturing Systems
Optical fiber sensing delivers a competitive edge in modern production and process environments. Proximion’s fiber-optic temperature, strain, and heat flux sensors allow for non-intrusive monitoring in electromagnetically noisy or high-temperature conditions.
These sensors are used in:
- Steel casting and moulding process.
- Liquid and gas storage.
- Industrial automation and process control.
- Cryogenic or high-voltage environments.
By replacing traditional electrical sensors with fiber-based alternatives, operators gain real-time insight without electromagnetic interference, improving quality, efficiency, and safety.

Aerospace and Defence
Aerospace and defence applications demand technologies that withstand extremes of temperature, acceleration, and vibration — without loss of accuracy and high reliability.
Proximion’s Fiber Bragg Grating sensors deliver precise mechanical and thermal data for aircraft, spacecraft, and propulsion systems. Furthermore, due to the simple addition of multiple FBGs in one fiber, a single fiber provides a multitude of sensing points, allowing distributed sensing of parameters with high temperature and spatial resolution. The additional advantage of FBG sensors being immune to EMI further makes our solutions not only easy to implement, but extremely flexible.
Our microwave photonic filters and optical time-delay chirped FBG solutions enhance radar, satellite, and secure communication capabilities, important for RF over fiber communications. Proximion’s unique capability of fabricating custom and long chirped FBGs provide customers in the radar and RF field with a flexible tool to realise optical signal processing solutions for RF communications.
These photonic technologies provide the lightweight, high-bandwidth, and EMI-immune performance essential for next-generation aerospace and defence systems.

Medical and Life Sciences
Photonics underpins much of modern medical imaging and diagnostic innovation.
Proximion’s chirped FBG technology enhances swept light sources for optical coherence tomography (OCT) systems to allow high-resolution, non-invasive imaging essential in areas of diagnosis and pharma development.
Additionally, our chirped FBG technology allow the realisation of ultrafast optical pulse systems to enable femtosecond laser surgery, time-resolved spectroscopy, and advanced imaging research.
Additionally, fiber-optic FBG sensors provide safe, EMI immune monitoring in sensitive environments such as MRI suites and operating rooms.

Chemical and Process Industries
Fiber-optic sensors deliver unique advantages in environments where heat, corrosion, or chemical exposure challenge traditional processes.
Proximion’s temperature and fluid-level sensors enable real-time monitoring of reactions and processes, improving safety and yield, bringing efficiencies and sustainable processes.
Cryogenic temperature FBG sensors provide precise temperature data for gas storage and low-temperature reactions, while heat flux sensors measure energy transfer during exothermic and endothermic processes.
All systems operate without electrical contact, making them safe for flammable, pressurized, or high-voltage environments.

Civil Engineering and Infrastructure
Structural safety depends on knowing how a structure behaves over time. Proximion’s distributed and array fiber-optic FBG sensors continuously monitor strain, deflection, temperature, and vibration across bridges, tunnels, dams, and rail networks.
Unlike point sensors, multipoint distributed systems detect changes along the entire structure, providing early warning of stress, settlement, or fatigue before visible damage occurs.
Proximion’s sensing systems provide integral monitoring to modern smart infrastructure projects, supporting sustainability and long-term resilience.

Scientific and Research Applications
Proximion’s FBG technologies are also tools of discovery. By virtue of our customer manufacturing processes, Proximion is able to tailor chirped frequency distributions to specific requirements. This is important in areas such as:
- Spectroscopy: Chirped FBGs exploit the dispersion to custom separate, group or isolate wavelengths for spectroscopic analysis.
- QKD: Chirped FBGs are used to provide positive and negative custom dispersion, to allow the spectral analysis of quantum light sources. The combination of positive and negative chirped FBGs together with phase modulators also allow optimum time-bin encoding of QKD signals for low bit-error rates (BER).
- Ultrafast pulse amplification: Custom chirped FBGs for stretching and compression of ultrafast optical pulses for optical amplification.
