The module is available in two different laser versions, C15 and E15. The standard wavelength is 1550 nm and the MIKRO is avilable with output wavelength anywhere in the 1535 to 1580 nm range. Moreover, the laser offers a wide thermal wavelength tuning range and can be combined with fast wavelength modulation e.g. for external stabilization. The lasers are available with PM (Polarisation Maintaining) or non-PM output.
For easy control, the MIKRO is available with an optional USB interface kit and can be controlled via NKTP CONTROL graphical user interface.
Features
- Compact OEM footprint
- Low phase noise and narrow linewidth
