Slow light with a swept-frequency source.
ct: We introduce a new concept for stimulated-Brillouin-scattering-based slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources. It allows slow light to be achieved, in principle, over the entire transparency window of the optical fiber. We demonstrate a slow light delay of 10 ns at 1.55 μm using a 10-m-long photonic crystal fiber with a source sweep rate of...
متن کاملFiber-length dependence of slow light with a swept-frequency source
We study the slow light effect via stimulated Brillouin scattering (SBS) using broadly-tunable frequency-swept sources, such as that used in optical coherence tomography. Slow light can be achieved, in principle, over the entire transparency window of the optical fiber (many 100’s of nm at telecommunication wavelengths). We demonstrate a SBS slow light delay of more than 1 ns over a wide bandwi...
متن کاملHigh-Coherence Wavelength Swept Light Source
[Summary] Optical technologies that have so far been restricted to the field of optical communications are now starting to be applied in new fields, especially medicine. Optical Frequency Domain Reflectometry (OFDR) offering fast and accurate target position measurements is one focus of attention. The Wavelength Swept Light Source (WSLS) is said to be one of the key devices of OFDR, whose sweep...
متن کاملHigh speed frequency swept light source for Fourier domain OCT at 20 kHz A-scan rate
We demonstrate a high-speed tunable, continuous wave laser source for Fourier domain OCT. The laser source is based on a fiber coupled, semiconductor optical amplifier and a tunable ultrahigh finesse, fiber Fabry Perot filter for frequency tuning. The light source provides frequency scan rates of up to 20,000 sweeps per second over a wavelength range of >70 nm FWHM at 1330 nm, yielding an axial...
متن کاملTechniques in Swept Frequency Capacitive Sensing: An Open Source Approach
This paper introduces a new technique for creating Swept Frequency Capacitive Sensing with open source technology for use in creating richer and more complex musical gestures. This new style of capacitive touch sensing is extremely robust compared to older versions and will allow greater implementation of gesture recognition and touch control in the development of NIMEs. Inspired by the Touché ...
