A depressed cladding waveguide with record low loss of 0.12 dB/cm is inscribed in YAG:Nd(0.3at.%) crystal by femtosecond laser pulses with an elliptical beam
10 Oct 2018 PDF | Depressed cladding waveguides have been formed in laser crystals by a tightly 10 mm long waveguide with core dimensions of. 100.
waveguides buried in lithium niobate crystal with shaped femtosecond laser pulses. Depressed cladding waveguides of variable mode-field sizes are fabricated7 Jul 2017 The depressed cladding-inscribed waveguides are permanent, but the propagation loss depends on the number of damage tracks. A track separation of ?1 ?m ? 1 ?m between adjacent damage tracks yields the lowest propagation loss of 0.5 dB/cm at 1550 nm for a 40 ?m diameter waveguide.
waveguides and waveguide splitters with laser-depressed cladding by femtosecond followed by a minor descent less than the filament length in the vertical.
Waveguide sizes: A = 116 µm, B = 110 µm, depth of waveguide center h = 120 µm. The red arrow indicates the propagation direction of inscribing beam.
