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.

For your application specific design the laser as a building block is also available in the Multi Project Wafer (MPW) Process Design Kit (PDK) of Idealphotonics.

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.

Available lasers

Currently We have lasers in the C-band available for their (OEM) customers with specification in table below. Optionally these are delivered with driving electronics and software including the user interface for easy operation.

Application

● Tunable diode laser absorption spectroscopy

● Lidar

● Long distance Fiber Communication
