By James F. Lowe, Web managing editor, james.lowe@photonics.comREHOVOT, Israel, Dec. 8, 2015 — Separating single photons from pulses of light could enable eavesdropping on encrypted quantum communications — and it could also help make such channels more secure. Researchers at the Weizmann Institute of Science have demonstrated how to pluck single photons out of light pulses using...Read full articleRelated content from Photonics MediaARTICLESSWAP Gate Could Help in Scaling Quantum ComputersThe quantum optics lab at the Weizmann Institute of Science has created a logic gate in which a photon and an atom can automatically exchange the information they carry.

They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass. Such...Photonics HandbookGaussian and Newtonian Thin Lens Formulas: Four important equations from which the image distance and the lateral magnification can be computed for an object at any arbitrary distance from a thin lens.Equation (1) is known as the Gaussian form of the lens equation, after the mathematician Karl F.
