NTT Photonics Labs Announces KTN Crystal Breakthrough

NTT Photonics Laboratories reported a breakthrough in its efforts to develop better optical waveguides. Researchers at NTT have synthesized a KTN crystals that could be used in optical modulators and optical switches with a driving voltage one order of magnitude lower than that of conventional optical devices. KTN is a transparent optical crystal composed of potassium, tantalum, niobium, and oxygen.
