Phenomenological studies of femtosecond laser ablation on optical thin films for integrated photonics
R. Peyton, V. Guarepi, G. A. Torchia
In this work, for the first time of our knowledge, we present a well-supported procedure to fabricate ridge optical waveguides onto thin films of PLZT by femtosecond laser ablation…
