Optical nanofibers

 A New Platform for Quantum Optics

Optical nanofibers (ONF), also called photonic nanowires, are specially processed optical fibers with diameters close to or below the wavelength of the guided light. The transmission can be maintained close to 100%.

We also respond to various requests from nano to micro-optical fibers, such as processing that prioritizes shape over loss. In addition to commercially available SMF specifications, PMF and MMF are available as special specifications.

Thermally Expanded Core Fiber

This is a technology that locally diffuses heat in the core of an optical fiber.

The mode field diameter of the optical fiber is locally thermally diffused. It can be used with commercially available SI type SMF. The mode field diameter is locally expanded by 2 or 3 times (the refractive index distribution changes) and the NA (numerical aperture) is reduced. The tolerance range for axis misalignment and gaps is expanded, and connection loss can be reduced. There is little change in cladding diameter, and it can be inserted into ferrules and used as a connector.

MFD conversion fiber (PMF compatible)

Connects optical fibers with different core diameters with low loss.

Normally, when optical fibers with different MFDs (optical fibers with different core diameters) are connected, MFD mismatch loss occurs.

By using our heat diffusion technology together, we reduce MFD mismatch loss to the absolute minimum. It can be used with commercially available SI type SMF. The joints are fusion spliced ​​and recoated or a reinforcing sleeve is attached. In addition to SMF specifications, some PMF and MMF can be applied as special specifications.
