Revolutionizing Photonics: The 1550nm DFB Laser Built for Demanding Applications
At Shijia Photons, our 1550nm DFB laser series showcases groundbreaking laser technology with ultra-stability, high power, and narrow linewidth characteristics. Whether you are designing FMCW LiDAR LiDAR chip systems, deploying 400G+ coherent networks, or monitoring critical infrastructure, our solutions are meticulously engineered to deliver superior performance.
Why Our 1550nm DFB Lasers Stand Out
Precision Power
- 100kHz Ultra-Narrow Linewidth: Achieve phase-sensitive applications like coherent communications and FMCW LiDAR LiDAR chip with near-zero signal distortion.
- Up to 200mW Output Power: Extend transmission distances and enhance signal-to-noise ratios, even in harsh environments.
- Butterfly & TO Packaging: Choose compact TO packages for cost-sensitive designs or rugged butterfly modules (TEC-integrated) for industrial-grade reliability.
Built for Real-World Challenges
- SBS Suppression Technology: Our proprietary quantum-well design minimizes Stimulated Brillouin Scattering (SBS), enabling stable operation at maximum power.
- Durability: Range of -40°C to +85°C, validated by third-party testing.
Plug-and-Play Integration
- Pre-calibrated drivers and industry-standard pinouts reduce development cycles by 30%.
- Custom wavelength options (C-band tunable) and OEM/ODM support available.
Applications Driving Innovation
- LiDAR & Autonomous Vehicles: Enable 300m+ detection range for FMCW LiDAR with 100kHz linewidth coherence.
- Telecom & Datacom: Power 400G ZR/ZR+ coherent modules for metro and submarine networks.
- Fiber Sensing: Detect sub-millimeter pipeline leaks or structural cracks with DAS/Φ-OTDR systems.
- Quantum Tech: Low-noise performance for QKD and atomic clock applications.
Why Engineers Trust Shijia Photons
- ISO 9001 & RoHS Certified: Rigorous quality control from chip epitaxy to final assembly.
- Fast Prototyping: Receive samples within 14 days (NRE fees waived for bulk orders).
