New Medical Light Source using NTT’s Communication Laser Technology

NTT-AT to sell the highest -speed wavelength swept light source that reduces the impact of diagnostic imaging on patients - NTT Advance Technology Corp. (hereinafter: NTT-AT; head office: Shinjuku-ku, Tokyo; President and CEO: Takashi Hanazawa) has started selling a 1.3-μm-band wavelength swept light source for use in optical coherence tomography (OCT) on February 1. OCT is a non-invasive in vivo imaging technique that is widely used in clinical applications. NTT-AT has developed this product using the same technology employed in the manufacture of an electro-optic crystal called KTN (potassium tantalate niobate: KTa1-xNbxO3) developed for use in telecommunications by Nippon Telegraph and Telephone Corporation (hereinafter: NTT; head office: Chiyoda-ku, Tokyo; President and CEO: Hiroo Unoura). The product is a marriage between this technology and high-speed variable wavelength laser technology that uses the crystal. Achieving a wavelength sweep speed of 200 kHz, the world’s fastest (double that of conventional products), this light source will speed up OCT-based examinations, significantly reducing the physical impact on patients. NTT-AT manufactures this product and markets it a company which has significant involvement in the manufacture and sale of medical devices and has a global sales network. The two companies will work together in selling wavelength swept light sources for OCT, and undertake joint development in order to augment their product portfolios and facilitate mass production, thereby expanding their presence in the medical device market. This light source will be exhibited at the Optical Fiber Communication Conference and Exposition (OFC/NFOEC 2013), America’s largest optical products trade show, opening on March 19, 2013 in Anahaim, California, U.S.A.
