Chilas, founded in 2018, has developed and produced ultra-narrow linewidth tuneable external cavity lasers. Their lasers are used in a wide range of applications such as coherent optical communications, LiDAR, Fibre Sensing and for sensors in the Oil Industry.
Their unique combination of ultra-narrow linewidth with a wide tuning range allows their lasers to have a swept source functionality. Furthermore, due to low cavity loss and long optical cavity length, Chilas’ laser can achieve high output power (>40 mW) and ultra-narrow linewidth (<1 kHz) at a competitive price compared to lasers with similar specifications.
Below is a schematic layout of one of the Chilas CF3 laser:
There are 3 heaters in the laser, one controls the phase of the light in the cavity, and two control the resonant wavelengths of the ring resonators Ring 1 (R1) and Ring 2 (R2), which in turn control the output wavelength. The laser’s frequency can be tuned over a large range by MRR tuning.
Each laser is housed in a compact, 14-pin butterfly package, enabling compatibility with any standard 14-pin laser diode mount.
