Why Maxer Photonics
We set the benchmark for what’s possible with photonics.
17 years powering the future of photonics.
Since 2009, we’ve been developing advanced fiber optic systems, photonic components and precision technologies for demanding real-world applications.
Precision engineering is the standard we build to.
Our in-house expertise combines optical design, electronics, precision assembly and advanced testing to deliver reliable photonic systems.
Behind every component is a complete system.
From concept and design to manufacturing and testing, Maxer Photonics develops the technologies that connect every stage of the photonics ecosystem.
What We Do
From optical components to complete photonic systems.
We design, develop and manufacture photonics technology across five areas — optical sources, fiber optic components, optical measurement, fiber optic testing and photonic integration — combining optics, electronics, firmware and mechanics into one connected engineering process, under one roof.

01
Precision Optical Sources
Broadband optical sources are a foundation of modern photonic systems. We develop SLED-based sources for broad spectral coverage, low coherence noise and stable output — paired with precision current control and thermal stabilization to hold performance steady as conditions change.

02
Polarization-Maintaining Technology
PM fiber components preserve a defined polarization state throughout the optical path — essential for sensitive interferometric and sensing systems. Our couplers, isolators and collimators hold extinction ratios up to 38 dB across operating temperatures from -40 °C to 70 °C.

Optical Measurement & Testing
From power monitoring to full chip characterization, our platforms bring optical, electrical and thermal test into one workflow — Optixor covers 800–1700 nm across up to 10 channels; Elphos tests SLED and DFP chips in butterfly packages before final assembly.

Where photonics becomes practical.
Optical Coherence Tomography
Broadband light reveals cross-sectional structure beneath a surface — a wider, more stable source spectrum resolves finer detail.
Interferometric Measurement
Comparing a reference path against a measurement path turns imperceptibly small physical changes into measurable signals.
Biomedical Imaging
A stable, well-characterized source is what keeps a diagnostic reading consistent, scan after scan.
Optical Communication
Data moves as light through fiber — engineered for high speed, low loss, long distance and multiple channels at once.
Industrial Monitoring & Automation
Fiber-based sensing keeps measurement electronics out of electrically noisy, high-vibration, high-heat environments.
Scientific Research & Metrology
When an experiment outgrows an off-the-shelf instrument, we build or adapt the source, detector or test setup around it.
Fiber Optic Sensing
The fiber itself becomes the sensor — temperature, strain, vibration and pressure all leave a signature in the returning light.
Custom Development
From concept to engineered system.
Every custom photonic system follows the same disciplined process — coordinating optical, electronic, fiber, thermal and mechanical engineering into one connected outcome.

Understanding the optical and system requirements a solution has to satisfy.
02
Optical Design
Working through the underlying optical principles and architecture.
03

A concept becomes hardware, measured and refined iteration by iteration.
05

Optical, fiber, electronic, thermal and mechanical layers brought together as one system.
06

In-House Electronics
Electronics built for photonics.
Our photonic systems are supported by in-house electronic design, embedded control and custom hardware development. Precision analog circuits, low-noise current control, FPGA-based architectures and dedicated test electronics — whichever the application actually calls for, it's built specifically for that system rather than adapted from a general-purpose board.

Advanced Packaging
Where photonics meets precision electronics.
Photonic performance does not end at the chip. Interconnect geometry, wire bonding, thermal paths, electrical design and mechanical assembly all influence the final system, which is why our engineering work has to span all of these layers, not just the optics.

Quality
Quality you can rely on.
Every Maxer Photonics product is tested and verified before it leaves our facility. That means precision measurement, environmental testing and long-term reliability checks against optical performance, electrical characteristics, thermal stability and system-level behavior — not just a pass/fail at final inspection.
