Abstract: Based on refractive index W-profile, two kinds of single-mode fibers are proposed: polarizing (bend type) and linear polarization maintaining (PM-fiber) with low losses (up to 0.35 dB/km). The polarizing W-fiber allows one to combine the dichroism in wide spectral range with opportunity to have almost any desirable mode field diameter (MFD). The PM-fiber low losses are essentially determined by fundamental mode tight packing in the guiding core. These fibers also can be made radiation resistant by replacing the germanium silicate core by nitrogen-doped core.
