Optical Materials

Using natural and synthetic quartz as a base, we have developed a wide array of optical materials such as synthetic quartz preform for optical communication and various optical parts. We also supply a wide range of products from raw materials to finished products.

 

Optical Materials

 

Synthetic quartz preform for optical fibers
Synthetic quartz preform is one of the product groups of Shin-Etsu Chemical that specializes in silicon chemical business. It is a rod based on synthetic quartz of high purity. The inner structure is designed so precisely that any incident light passes through without attenuation. Shin-Etsu Chemical has built a new factory in Kashima, Ibaraki Prefecture, which started operation in October 2001. The production capacity has since doubled, further establishing a system of stable supply.

Features
  • The high-level and complex production process is backed by highly reliable quality control and computer technology, ensuring a stable and high quality.
  • We were the first company to produce large-size preforms, and established mass production technology for preforms 160mmφ in diameter ×1,500 mm in length.

 

Applications
  • Fibers for optical communication, image guides, and laser transmission

Synthetic quartz glass for optics
Production technology of optical quartz glass introduced from Heraeus Quarzglas GmbH, Germany together with the excellent synthetic technology of Shin-Etsu Group are the base of development of this synthetic optical quartz glass.

Features
  • Unlike natural quartz glass, this product has no granular structure and does not emit fluorescence under a 253.7 nm mercury lamp.
  • Various grades are available depending on the presence or absence of striae, light transmittance, and laser-proof property.

 

Applications
  • Lens materials for excimer laser steppers
  • Spectrum prism, lens, windows, mirror for laser, etc.

Optical fiber coatings
The coating prevents the additional loss of optical information that travels through the optical fiber (quartz glass) by constant reflection caused by microbending. Thus, the coating improves transmission characteristics and also protects the optical fibers against mechanical stress such as lateral pressure applied to the optical fiber.

Features
  • Liquid silicone rubber is the raw material, which is highly resistant to heat and cold and shows stable performance over a wide range of temperatures.

 

Lineup
  • For primaries, for buffers, for polymer clads
  • Two types of curing methods are available; heat curing type and UV curing type suitable for high-speed drawing.

Highly transparent coating for optical networks
The Opticlear series are developed by the original technologies of Shin-Etsu Chemical. They are used to protect and coat various parts or modules in optical networks, and also as a highly transparent and refractive material for use in optical waveguide.

Features
  • It has excellent transparency and heat resistance.
  • Refraction index can be adjusted over a wide range with high precision.

 

Applications
  • For refraction index matching, protection, and coating of optical joints
  • As waveguide materials for optical devices

Optical isolators
The optical isolators are highly reliable optical passive parts, the key components of which are manufactured by Shin-Etsu Chemical. Used in laser modules that forms the light source of optical communication and in joints of optical fibers, they support stable high-speed communication.

Features
  • They take pride in compactness and high reliability.
  • The Faraday Rotators developed by Shin-Etsu Chemical's oxide single crystal growing technology is used.
  • Shin-Etsu Chemical's Sm-Co magnet is used.
  • Isolators for 1.31μm, 1.48μm and 1.55μm are included in the lineup. Single type and double type are available.

 

Applications
  • They are incorporated in DFB laser modules used in optical fiber networks (relay system, CATV), and cut the reflected light.
