Waveguide Materials

PQL has deposited high quality waveguiding alumina layers that appeared to be unaffected by ultraviolet irradiation – a requirement for the "next generation" of upconversion lasers using thulium as the active laser ion.

We have achieved excellent results through reactive sputtering:

• High deposition rate of High quality alumina
• RI very near to bulk properties
• Zero breakdown
• Very low stress films (controlled through process conditions)
• Deposition onto plastic and delicate substrates
• Also low rate deposition
• UV stable
