Shane: Tourette
No full textShane Fistel is a talented sculptor and painter. He also suffers from Tourette's syndrome, that often-misunderstood condition that historically has been misdiagnosed as insanity and even demonic possession. In this program, neurologist/author Oliver Sacks explores his unique friendship with Shane. Together, they travel to the Charcot Library at the Salp?tri?re in Paris to learn more about Tourette's syndrome. This condition, first described in 1885 by Jean-Martin Charcot's colleague Gilles de la Tourette, is a neurochemical disorder. Due to its influence, Shane?a charismatic individual totally lacking in social inhibitions?feels compelled to act in ways that others find antisocial and threatening

Quantum micro–nanodevices fabricated in diamond by femtosecond laser and ion irradiation
No full textDiamond has attracted great interest as a quantum technology platform due to its optically active quantum emitters such as the negatively charged nitrogen-vacancy center. The nitrogen vacancy’s ground state spin can be read out optically, with long millisecond spin coherence times at ambient temperatures. In addition, the energy levels of the nitrogen vacancy are sensitive to external fields. These properties make nitrogen vacancies attractive as a scalable platform for efficient nanoscale resolution sensing based on electron spins and for quantum information systems. Diamond photonics enhance optical interactions with nitrogen vacancies, beneficial for both quantum sensing and information. However, several useful building blocks for diamond quantum devices have been demonstrated, namely, photonics, quantum emitters, and micrographitic wires. In this chapter, an overview is provided of ion irradiation and femtosecond laser writing, two promising fabrication methods for diamond-based quantum technological devices. The unique capabilities of both techniques are described, and the most important fabrication results of quantum emitters, photonics, microfluidics, and microwires in diamond are reported, with an emphasis on integrated devices aiming toward high-performance quantum sensors and quantum information systems

Laser surface structuring of diamond with ultrashort Bessel beams
No full textWe investigate the effect of ultrafast laser surface machining on a monocrystalline synthetic diamond sample by means of pulsed Bessel beams. We discuss the differences of the trench-like microstructures generated in various experimental conditions, by varying the beam cone angle, the energy and pulse duration, and we present a brief comparison of the results with those obtained with the same technique on a sapphire sample. In diamond, we obtain V-shaped trenches whose surface width varies with the cone angle, and which are featured by micrometer sized channels having depths in the range of 10–20 μm. By laser writing crossed trenches we are also able to create and tailor on the diamond surface pillar-like or tip-like microstructures potentially interesting for large surface functionalization, cells capturing and biosensing

Visible to Infrared Diamond Photonics Enabled by Focused Femtosecond Laser Pulses
No full textDiamond’s nitrogen-vacancy (NV) centers show great promise in sensing applications and quantum computing due to their long electron spin coherence time and because they can be found, manipulated, and read out optically. An important step forward for diamond photonics would be connecting multiple diamond NVs together using optical waveguides. However, the inertness of diamond is a significant hurdle for the fabrication of integrated optics similar to those that revolutionized silicon photonics. In this work, we show the fabrication of optical waveguides in diamond, enabled by focused femtosecond high repetition rate laser pulses. By optimizing the geometry of the waveguide, we obtain single mode waveguides from the visible to the infrared. Additionally, we show the laser writing of individual NV centers within the bulk of diamond. We use µ-Raman spectroscopy to gain better insight on the stress and the refractive index profile of the optical waveguides. Using optically detected magnetic resonance and confocal photoluminescence characterization, high quality NV properties are observed in waveguides formed in various grades of diamond, making them promising for applications such as magnetometry, quantum information systems, and evanescent field sensors
