摘要： An optical fiber module includes a polarization-maintaining highly-nonlinear optical fiber and a housing. 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.
