In this paper, we report on the infrared luminescence of amorphous praseodymium-doped GeInSbSe waveguides, which can be used as infrared sources in photonic integrated circuits on silicon substrates. Amorphous chalcogenide thin films were deposited by radiofrequency magnetron cosputtering using an argon plasma whose deposition parameters were optimized for chalcogenide materials. The micropatterning as ridge waveguides of the chalcogenide cosputtered films was performed using photolithography and plasma-coupled reactive ion etching techniques.

Article Synopsis
  • A planar waveguide laser composed of 4.5 at.% Tm and 0.5 at.% Ho in LiYF, with a thickness of 25 μm, is pumped at 1679 nm using a Raman fiber laser.
  • The laser achieves a maximum output power of 540 mW at 2051 nm with a slope efficiency of 32.6% and requires a threshold of 337 mW, while maintaining linear polarization.
  • This system demonstrates the highest output power recorded for any Tm,Ho waveguide laser and exhibits low waveguide propagation losses of 0.19 dB/cm without any undesired Tm colasing.
