'Quantum Pointer' Improves Measurements
Oct 1, 2003 — An optical system called a "quantum laser pointer," developed by scientists at Australian National University in Canberra and at Université Pierre et Marie Curie in Paris, promises to improve measurements of the position of a laser beam. The system may have implications for microscopy and for the characterization of such phenomena as refractive index gradients. Nicolas Treps of the university in France explained that the quantum laser pointer is a beam of light in which the photons are...
Erbium-Doped Fiber Amplifier Displays Low Noise
Oct 1, 2003 — Most fiber optic systems operate in the 1530- to 1565-nm C-band because the gain of erbium-doped fiber amplifiers peaks in this spectral region. But as the demand for bandwidth grows, many telecom engineers look covetously at the 1565- to 1625-nm...
Fiber Laser Is Wavelength-Tunable for the S-Band
Oct 1, 2003 — A group at the National Chiao-Tung University in Hsinchu, Taiwan, has capitalized on recent successes with S-band erbium-doped fiber amplifiers to design and demonstrate a wavelength-tunable fiber laser for this telecommunications band. Wavelength-...
Mode-Locked Ring Laser Produces 274-fs Pulses
Oct 1, 2003 — Scientists at the University of Central Florida in Orlando have developed a "breathing mode" semiconductor laser with mode-locked, externally compressed 274-fs pulses. The approach promises semiconductor lasers capable of producing even shorter...
Crystals Compensate for Birefringence in Polymer
Oct 1, 2003 — The processing of optical polymers in the production of liquid crystal displays (LCDs) and lenses tends to produce birefringence in the materials. Manufacturers may compensate for this phenomenon by using alternative fabrication techniques, such as...
