Precision Photonics for Real-World Impact System-Level Impact
From autonomous sensing to quantum networks, Deeplight’s integrated photonic platforms deliver the coherence, speed, and stability your systems depend on.
Explore how our ultra-narrow linewidth, frequency-agile lasers and Kerr soliton frequency combs solve real application challenges across sensing, communications, and quantum technologies.
Distributed Fiber Optic Sensing
The Challenge
Pipelines, railways, and power grids require continuous monitoring over hundreds of kilometers. Conventional sensor networks are expensive to deploy and difficult to maintain. Failures are often detected too late after they escalate into costly incidents.
How Deeplight Helps
The DLT-FT-1550 delivers the long coherence length and ultra-low phase noise with fast tunability required for distributed acoustic sensing (DAS) and related fiber sensing methods.
-
50–100+ km monitoring from a single interrogation unit
-
< 1 m spatial resolution for precise event localization
-
High sensitivity to vibration, strain, and temperature changes
Your Advantages
You achieve a higher signal-to-noise ratio over long distances and detect events more reliably with greater sensitivity. You maintain stable performance across 50-100+ km sensing ranges.
FMCW LiDAR
The Challenge
Autonomous vehicles and robotic systems require long-range sensing beyond 500 meters with simultaneous distance and velocity measurement. Conventional time-of-flight LiDAR cannot extract velocity directly and struggles in dynamic environments. FMCW LiDAR solves this—when the laser source maintains high coherence and stable, linear frequency chirps.
How Deeplight Helps
Deeplight lasers provides the coherence and chirp stability FMCW LiDAR needs for clean beat signals and accurate Doppler extraction at long range.
-
Simultaneous range and velocity extraction in a single coherent measurement
-
Detection ranges beyond 500 m with high precision
-
Chip-scale integration for compact, scalable LiDAR modules
Your Advantages
You build a robust long-range FMCW LiDAR system with higher precision and better velocity fidelity. You maintain coherence across fast sweeps and support scalable, compact architectures.
Optical Communications & Satellite Links
The Challenge
Long-haul fiber networks and satellite optical links push data rates beyond 100 Gbps over 1,000+ km. Phase noise from conventional lasers limits coherent detection and increases bit error rates. In free-space links, turbulence and Doppler shifts further stress spectral purity.
How Deeplight Helps
The DLT-FT-1550 delivers sub 10 Hz intrinsic linewidth and phase noise down to –140 dBc/Hz, supporting advanced coherent modulation formats and stable long-distance transmission.
-
Higher signal-to-noise ratio for coherent receivers
-
Greater robustness in terrestrial and satellite optical links
-
Lower form factor and power consumption for space platforms
Your Advantages
You maintain link stability over long distances. You reduce error rates in demanding environments. You deploy compact, low-SWaP laser sources for space and ground systems.
Quantum Technologies
The Challenge
Quantum computing, communication, and sensing demand optical sources with ultra-low phase noise and long-term frequency stability. Even minimal drift degrades coherence and limits system performance. Researchers and system developers need scalable solutions from chip-level integration to fully packaged systems without compromising spectral purity.
How Deeplight Helps
Deeplight provides a full-stack photonic platform combining ultra-narrow linewidth lasers and Kerr frequency comb generators. Our integrated approach preserves coherence while supporting flexible system architectures.
