Fiber Coupled Tunable Laser Source Narrowline C-Band

SKU: NECL

The NECL Series tunable laser source is an InP-based, ultra-narrow linewidth External Cavity Laser (ECL) designed for high-performance optical applications. It integrates a semiconductor optical amplifier (SOA) for optical power amplification, shutter functionality, and power control. This architecture enables fast and precise wavelength tuning, making it ideal for coherent Dense Wavelength Division Multiplexing (DWDM) systems. The laser chip is maintained at a fixed temperature, eliminating thermal drift during tuning. Wavelength stability is ensured by an internal wavelength locker, which aligns output precisely to the 50 GHz or 100 GHz ITU grid and also provides real-time monitoring of front-facet power for feedback control to the SOA. The device comes with polarization-maintaining fiber to support integration with external modulators. The NECL laser is mounted on a driver board featuring variable power control, shuttered tuning, trace tone generation, and stimulated Brillouin scattering (SBS) dither circuitry, all accessible through an RS-232 interface. A turn-key benchtop version is available, offering high optical output power up to 200 mW.
