Ultra-narrow Linewidth Tunable Laser

Our tunable laser is a unique system. With this hybrid assembly approach to silicon-nitride based photonic integrated circuits we apply this technology in one system. This narrow-linewidth tunable laser has an ultra-narrow linewidth and is tunable over a the whole C-band. The combination of wavelength accuracy with tunability makes this external cavity laser an unique laser system.


Narrow linewidth lasers at the wavelength range around 1550nm are are perfect to use in telecom systems, OTDR systems and fiber bragg sensing systems.


The main concept follows from our hybrid assembly approach, that combines low- loss silicon-nitride PIC with active gain PICs. For this specific laser we attached a gain section PIC in InP technology hybridly to a tunable reflector PIC creating an external cavity laser. The gain section creates the first mirror and the necessary gain, the silicon-nitride based TriPleX™ PIC acts as a tunable wavelength dependent mirror.


We are able to customize our laser to the requirements of your application. For our of-the-shelve version of this we have a standard specification sheet. Highlight of these specifications are:

  • Fiber output power : >13dBm
  • Lorentz linewidth <10kHz
  • Tunable over 1530-1565 nm

Other wavelengths and ASIC

The tunable laser is well suited for customization. To create custom features we integrated additional application specific functions on the same TriPleX™ PIC. For your application specific design we also have the laser available as a building block in the Multi Project Wafer (MPW) Process Design Kit (PDK) of LioniX International. And since the TriPleX works from 405 to 2350nm you can easily adapt the concept to other applications, requiring different wavelengths bands.
