Journal ArticleDOI
Long, low loss etched As(2)S(3) chalcogenide waveguides for all-optical signal regeneration.
Steve Madden,Duk-Yong Choi,Douglas Bulla,Andrei Rode,Barry Luther-Davies,Vahid G Ta'eed,Mark Pelusi,Benjamin J. Eggleton +7 more
TL;DR: It is found that the ratio of nonlinearity and dispersion linearizes the pulse chirp, reducing the spectral oscillations caused by self-phase modulation alone and giving rise to a nonlinear transfer function suitable for all-optical regeneration of high data rate signals.
Journal ArticleDOI
Photonic-chip-based radio-frequency spectrum analyser with terahertz bandwidth
Mark Pelusi,Feng Luan,Trung D. Vo,Michael R. E. Lamont,Steven J. Madden,Douglas Bulla,Duk-Yong Choi,Barry Luther-Davies,Benjamin J. Eggleton +8 more
TL;DR: In this article, a planar chalcogenide waveguide is demonstrated to be able to perform radio-frequency spectral measurements with a terahertz bandwidth and high bit-rate tests show that the chip-based system is potentially useful for ultrafast signal processing.
Journal ArticleDOI
Applications of Highly-Nonlinear Chalcogenide Glass Devices Tailored for High-Speed All-Optical Signal Processing
Mark Pelusi,Vahid G Ta'eed,Libin Fu,Eric Magi,Michael R. E. Lamont,Steven J. Madden,Duk-Yong Choi,Douglas Bulla,Barry Luther-Davies,Benjamin J. Eggleton +9 more
TL;DR: In this paper, a planar rib waveguide with nonlinearity up to 2080 W-1ldr km-1 and losses as low as 0.05 dB/cm has been developed to enable high-speed all-optical signal processing in compact, low-loss optical devices through the use of ultra fast Kerr effect.
Journal ArticleDOI
Progress in optical waveguides fabricated from chalcogenide glasses
Xin Gai,Ting Han,Amrita Prasad,Steve Madden,Duk-Yong Choi,Rongping Wang,Douglas Bulla,Barry Luther-Davies +7 more
TL;DR: The fabrication processes and properties of waveguides that have been made from chalcogenide glasses including highly nonlinear waveguide developed for all-optical processing are reviewed.
Journal ArticleDOI
Local tuning of photonic crystal cavities using chalcogenide glasses
Andrei Faraon,Dirk Englund,Douglas Bulla,Barry Luther-Davies,Benjamin J. Eggleton,Nick Stoltz,Pierre Petroff,Jelena Vuckovic +7 more
TL;DR: In this article, the MURI Center for photonic quantum information (MURI Center of Photonic Quantum Information (PQI) at the Australian Research and Universities Council Centre of Excellence (CUDOS) was used to perform experiments at Stanford Nanofabrication Facility.
