We’re thrilled to congratulate our long-time partner, SemiNex Corporation, on receiving a Silver Honoree in the prestigious 2025 Laser Focus World Innovators Awards! Their groundbreaking High Power Narrow Linewidth External Cavity Laser (ECL) diode stood out for its superior performance, innovative design, and ability to push boundaries in photonics technology—surpassing traditional Distributed Feedback (DFB) lasers in key areas like output power and noise reduction.
This award-winning ECL delivers >200 mW fiber-coupled power with an ultra-narrow <3 kHz Lorentzian linewidth, low Relative Intensity Noise (RIN), and exceptional Side Mode Suppression Ratio (SMSR). Built on SemiNex’s proprietary Gain Chips and Semiconductor Optical Amplifiers (SOAs), it offers single-frequency operation in C-band or O-band wavelengths, making it ideal for demanding applications such as:
- FMCW LiDAR for extended-range autonomous systems and automotive sensing
- Optical networks and fiber sensing in telecommunications
- Aerospace and high-precision navigation
- Quantum sensing, industrial metrology, and emerging quantum computing
Packaged in a reliable 14-pin butterfly format (with swept-wavelength options available), this ECL ensures seamless integration, stability, and durability in harsh environments.
