communication made it possible to transmit massive volumes
of information by multiple wavelength transmission.
Recently, much attention has been focused on fiber grating,
which can selectively extract and add specific wavelengths.
Fiber grating, an optical fiber with a special structure
(diffraction grating) made by applying ultraviolet laser
rays to vary the refractive index by a pitch of about
0.5 microns, acts as a filter for optical signals with
specific wavelengths. In this program, students learn
basic optic theories concerning refraction and reflection
and experience how optical fiber grating is made. They
can also study such topics as how to connect and measure
optical fibers. We welcome students interested in monozukuri
and in handling precision devices to which they have
not yet been exposed. |
