Journal ArticleDOI
Unusual angular dependence of the Raman response in black phosphorus.
H. B. Ribeiro,Marcos A. Pimenta,Christiano J. S. de Matos,Roberto L. Moreira,Aleksandr Rodin,Juan D. Zapata,Juan D. Zapata,Eunézio A. Thoroh de Souza,Antonio H. Castro Neto +8 more
TL;DR: It is shown that the angular dependence of polarized Raman spectra of BP is rather unusual and can be explained only by considering complex values for the Raman tensor elements.
Journal ArticleDOI
Efficient graphene saturable absorbers on D-shaped optical fiber for ultrashort pulse generation
Juan D. Zapata,Juan D. Zapata,David Steinberg,Lucia A. M. Saito,R. E. P. de Oliveira,Ana M. Cardenas,E. A. Thoroh de Souza +6 more
TL;DR: A criterion between the polarization relative extinction ratio in the samples and the pulse duration relates the better mode-locking performance with the higher polarization extinction ratio of the samples, which provides a better understanding of the graphene distributed saturable absorbers.
Journal ArticleDOI
Mechanically Exfoliated Graphite Onto D-Shaped Optical Fiber for Femtosecond Mode-Locked Erbium-Doped Fiber Laser
TL;DR: In this article, a femtosecond mode-locked Erbium-doped fiber laser (EDFL) was reported by using mechanically exfoliated graphite deposited onto a D-shaped optical fiber.
Journal ArticleDOI
Graphene oxide and reduced graphene oxide as saturable absorbers onto D-shaped fibers for sub 200-fs EDFL mode-locking
David Steinberg,Rodrigo M. Gerosa,Fernanda N. Pellicer,Juan D. Zapata,Sergio H. Domingues,Eunézio A. Thoroh de Souza,Lucia A. M. Saito +6 more
TL;DR: In this paper, the authors present high mode-locking performances from an erbium-doped fiber laser (EDFL) by using reduced graphene oxide (r-GO) as saturable absorbers (SA) deposited onto the polished surface of a D-shaped optical fiber.
Journal ArticleDOI
Raman Mapping Characterization of All-Fiber CVD Monolayer Graphene Saturable Absorbers for Erbium-Doped Fiber Laser Mode Locking
Henrique G. Rosa,David Steinberg,Juan D. Zapata,Lucia A. M. Saito,Ana M. Cardenas,José C. V. Gomes,Eunézio A. Thoroh de Souza +6 more
TL;DR: In this article, the characterization and quality evaluation of all-fiber chemical vapor deposition (CVD) graphene saturable absorber samples for Erbium-doped fiber laser (EDFL) mode locking is presented.
