Distributed Acoustic Sensing (DAS)
DAS transforms standard optical fiber into thousands of distributed acoustic sensors. By sending laser pulses into a fiber and detecting Rayleigh backscattering, DAS systems can detect vibrations with meter-scale resolution over tens of kilometers.
- Long-range, high-resolution phase sensitivity
- Low phase noise for accurate signal recovery
- Ideal for infrastructure monitoring, seismic detection, and perimeter security
Brillouin Sensing
Brillouin sensing leverages the interaction between light and acoustic phonons in optical fiber to measure strain and temperature. High-resolution measurements require extremely narrow linewidth lasers to resolve small frequency shifts in the Brillouin spectrum.
- Excellent frequency stability for Brillouin scattering resolution
- Fine wavelength tuning and narrow linewidths
- Deployed in structural health monitoring and geotechnical sensing
LIDAR
LIDAR systems use laser light to map environments by measuring the time-of-flight or frequency shift of reflected beams. Coherent and frequency-modulated continuous wave (FMCW) LIDAR require lasers with excellent phase stability and fast tunability.
- High coherence for long-range distance measurements
- Fast tuning and modulation capabilities
- Applications in autonomous vehicles, robotics, and 3D mapping
Quantum Applications
Quantum technologies rely on ultra-stable lasers for manipulating atomic states, enabling quantum computing, precision sensing, and secure communications. IOPTIS lasers are used in coherent population trapping (CPT), electromagnetically induced transparency (EIT), and optical clocks.
- Sub-10 kHz linewidths for atomic spectroscopy and laser cooling
- Wavelength stability and tunability for CPT, EIT, and Raman transitions
- Trusted by academic and national labs for quantum sensing and computing
Spectroscopy and Metrology
High-resolution spectroscopy and precision optical metrology demand lasers with exceptional frequency stability and narrow linewidths. IOPTIS lasers are suited for gas spectroscopy, frequency standards, and calibration systems.
- Ultra-narrow linewidth for Doppler-free and saturated absorption spectroscopy
- Wavelength tunability across telecom bands
- Used in calibration of wavemeters and frequency combs
RF and Microwave Photonics
IOPTIS lasers are used in photonic systems that generate, process, or detect RF and microwave signals through optical components. These applications benefit from low phase noise and high coherence.
- Ideal for optical heterodyning and microwave signal generation
- Supports photonic signal distribution and phased arrays
- Used in advanced radar and communication platforms
Coherent Communications
In coherent optical communication systems, lasers must offer extremely narrow linewidth and low phase noise for advanced modulation schemes. IOPTIS lasers enable high-capacity, long-distance data transmission.
- Support for QPSK, QAM, and coherent detection systems
- Ultra-low linewidth improves bit-error rates
- Compatible with tunable transceivers and optical coherent receivers
