摘要： A dispersion compensating optical fiber is proposed for application in a wavelength optical signal transmission system. This dispersion compensating fiber has a W shaped refractive index profile, and has a first core layer, a second core layer formed around the outside of the first core layer, and a cladding layer made of substantially pure silica formed around the outside of the second core layer. The first core layer is doped with germanium, so that its refractive index s increased by a proportional refractive index difference of about 2%. The second core layer is uniformly doped with fluorine, so that its refractive index is decreased by a proportional refractive index difference of about 0.58%. The ratio of the outer radius of the second core layer to the outer radius of the first core layer is about 2.5. The wavelength dispersion slope is in the negative region, the dispersion is made to be high negative dispersion, and moreover the dispersion slope compensation ratio from a wavelength of 1530 nm to a wavelength of 1570 nm is made to be a value close to the perfect dispersion ratio and about 0.75 to 1.25 thereof.

The polarization-maintaining highly-nonlinear optical fiber includes a core, a cladding surrounding the core and having two stress applying portions formed to sandwich the core and extend along the core, and a coating covering the cladding. The housing houses the polarization-maintaining highly-nonlinear optical fiber which is wound in a ring coil shape. The polarization-maintaining highly-nonlinear optical fiber has a bending loss of 0.01 dB/turn or less at a wavelength of 1550 nm when bent to form a diameter of 20 mm, a nonlinear coefficient γ of 10 W1 km−1 or larger at the wavelength of 1550 nm, a cutoff wavelength λc of 1530 nm or shorter, and a zero-dispersion wavelength of not shorter than 1400 nm and not longer than 1650 nm.
