Chilas has developed a compact narrow-linewidth widely tunable laser module based on their hybrid-integration external cavity laser (ECL) technology. This new laser is perfectly suited for a large range of sensing applications like structural health monitoring using Fiber Bragg gratings, molecular detection using ring resonators, and LiDAR remote sensing.

Seamlessly sweeping and widely tunable : Featuring a fiber output power exceeding 10 mW, this laser is capable of sweeping across the entire C-band (1528-1568 nm) at speed of 40 nm per second. While the laser currently operates in a static mode, a dedicated driver and improved calibration procedures allow for quasi-continuous sweeping across the full tuning range.

A key feature of this laser is its ultra-fine wavelength grid of 4 pm, which ensures precise coverage of all wavelengths within its range. The laser is designed to sweep without mode hops over each 0.2 nm segment, with only a brief 1 millisecond pause as it transitions to the next segment.

The laser’s innovation lies in its fully chip-based wavelength filter, a design that eliminates the need for mechanical moving parts. This design offers significant advantages:
1. Instantaneous Range Reset The laser can switch from the end of its scan range back to the start without any delay, resulting in a nearly 100% duty cycle.
2. Consistency & Repeatability The consistency from scan to scan is excellent, making this laser highly reliable for high-volume demands

This laser module is compact, housed in a unit measuring just 100x60x20 mm. It features an extended-cavity diode laser and includes all necessary electronic drivers. The module is equipped with a DB9 connector, and a USB interface can be supplied on request. Plus, the included software makes it easy to control and adapt the laser to specific needs.
