Wavelength and duration tunable 10 GHz 1.3ps pulse source using dispersion decreasing fiber based distributed Raman amplification [PDF]

, 2004
We experimentally demonstrate a novel pulse compression scheme using dispersion decreasing fiber (DDF) based distributed Raman amplification. We adiabatically compress 10GHz, 13ps seed pulses generated using a commercially available electro-absorption ...

Noise-Like Pulse Generation Using Polarization Maintaining Mode-Locked Thulium-Doped Fiber Laser With Nonlinear Amplifying Loop Mirror

IEEE Photonics Journal, 2019
We investigate noise-like pulse (NLP) generation in a mode-locked thulium-doped fiber laser with nonlinear amplifying loop mirror (NALM) and different net anomalous dispersions.

Generation of noise-like pulses with 203 nm 3-dB bandwidth

Optics Express, 2019
Raman-scattering-assisted noise-like pulse (NLP) generation was achieved by using an appropriate segment of high nonlinearity fiber in an erbium-doped fiber laser. Broadband spectrum with 203 nm 3-dB bandwidth was obtained, which, to the best of our knowledge, is the broadest bandwidth achieved for NLPs.

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Versatile patterns of multiple rectangular noise-like pulses in a fiber laser

Optics Express, 2016
We report on the generation of versatile patterns of multiple rectangular noise-like pulses (NLPs) in a fiber laser mode-locked by nonlinear amplifying loop mirror (NALM). Benefiting from the strengthened nonlinear effect of a segment of highly nonlinear fiber (HNLF) in the loop, multiple rectangular NLPs with various patterns are formed depending on ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Systematic Approach to Optimum Chip Pulse Shape Design [PDF]

, 2008
In this work we establish a systematic approach to design optimum chip pulse shapes for DS-CDMA systems which are absolutely bandlimited, whose energy is mainly concentrated in one chip duration, and thatminimize the Cramer-Rao lower bound for the ...

Noise in and as music [PDF]

, 2013
One hundred years after Luigi Russolo’s “The Art of Noises,” this book exposes a cross-section of the current motivations, activities, thoughts, and reflections of composers, performers, and artists who work with noise in all of its many forms.
