Post-deadline paper on narrow linewidth tunable laser

CLEO US  has accepted our post deadline abstract for its conference from 14 – 19 May, San Jose, CA, USA. With Youwen Fan (University of Twente, MESA+ Institute for Nanotechnology)  as main author we’re proud that LioniX International co-authored this excellent work.

With its title “290 Hz intrinsic linewidth from an integrated optical chip-based widely tunable InP-Si3N4 hybrid laser” the work can be called revolutionary. The authors present an integrated chip-based InP-Si3N4 hybrid laser with unprecedented high spectral-purity. A record-narrow fundamental laser linewidth of 290 Hz with a widest-ever spectral coverage (81 nm at 1550 nm) is experimentally demonstrated.

Ultra Narrow linewidth tunable laser available

LioniX International has developed a narrow line-width tunable laser based on a hybridly integrated external cavity laser. The concept uses state-of-the-art Photonic Integrated Circuit (PIC) technology and has distinctive advantages of which the most important are:

–  Ultra narrow line width

–  Broadband tuning

–  Small footprint/size

External cavity tunable laser

The main concept is shown in the figure below: A gain section PIC is hybridly attached to a tunable reflector PIC creating an external cavity laser. The gain section creates the first mirror and the necessary gain, the silicon nitride (Si3N4) based TriPleX™ PIC acts as a tunable wavelength dependent mirror.

Additional application specific functions can be integrated on the same TriPleX™ PIC to create custom features.

 Towards other applications

Another advantage of this approach is that the technology can be used in other than C-band applications. Gain section PICs are available in ranges in the VIS, NIR and MIR as well. TriPleX™ operates over broad bandwidth of 405 to 2350 nm.
