NTT-AT, which inherited the technologies of NTT Laboratories, has developed a range of optical adhesives and optical resins along with the advancement of optical communication technologies. In order to realize highly reliable optical components, there must be superior adhesive and resin that can be easily solidified and have excellent durability. NTT-AT has developed and commercialized adhesives and resins that satisfy the customers’ requirements including not only adjustability of the index of refraction suitable for optical connection, but also precise fixation, heat resistance, high elasticity and low moisture permeability; these features are all effective for stable connections with low loss. Furthermore, NTT-AT provides important optical components such as an optical modulator used for multiple wavelength optical communication, which meets the demand for high-capacity optical networks, and wave plates that are superior in transparency in the range of wavelength used for optical communication. In addition, these plates are made of polyimide with high heat resistance and high chemical resistance to withstand soldering; and the plates of 1/2λ wavelength and 1/4λ wavelength are available. They are thin-film wave plates essential for manufacturing a low loss modulator (e.g., Mach-Zehnder, QPSK) and AWG.

Please contact NTT-AT for maintaining an optical network system without poor connection or burnout accidents. The power of optical transmission becomes higher due to the increase of transmission data in an optical network. If there is a contamination or defect in the shape at the connection point of an optical network, the high power optical energy causes burnout and can lead to a serious accident of communication error due to the failure in damaged network devices in a network system. NTT-AT provides the connector cleaners and the polishers that are designed and manufactured with the deepest consideration and from actual feedback from communication construction sites - those products protect leading-edge optical networks. The optical network supports rapidly increasing communication throughout the world. And architecture and maintaining tools that support the optical network are NTT-AT's products.

For Preventing pattern collapse
High-power ICs (integrated circuits) and high frequency communication ICs with high efficiency and low power dissipation are in great demand. NTT-AT provides high-quality GaN epitaxial wafers that satisfy the challenging requirements of such products. We produce epitaxial wafers which we insure are aligned with the design concepts of IC chip manufacturers. In addition, we are constantly engaged in essential consideration of leakage current reduction and collapse reduction by precisely controlling epitaxial growth conditions and maintaining a stable process based on know-how and many years of accumulated technology, inherited from NTT laboratories. We have prepared a wafer production system appropriate for the requirements of high uniformity for R&D, and stable mass production of commercial products. NTT-AT is not an IC chip manufacturer, but NTT-AT has knowledge of IC chips from its research activities. NTT-AT is a partner of IC chip manufacturers and attentively supports them as customers. Please feel free to discuss with NTT-AT about GaN HEMT epitaxial wafers.
