We describe the femtosecond inscription of waveguides in z-cut lithium niobate using the multi-scan technique. The form of modified regions and their relationship with writing pulse energy and scan speed is examined. An insertion loss of 3.5dB at 1550nm was measured for an 18mm long waveguide coupled to single-mode fibers.

Abstract
We describe the femtosecond inscription of waveguides in z-cut lithium niobate using the multi-scan technique. The form of modified regions and their relationship with writing pulse energy and scan speed is examined. An insertion loss of 3.5dB at 1550nm was measured for an 18mm long waveguide coupled to single-mode fibers.File in questo prodotto:
