A segmented-cladding fiber (SCF), which consists of a uniform core of high refractive index and a cladding with regions of high and low refractive index alternating angularly, provides an effective approach for achieving widely extended single-mode operation with a large core size. Fabricating segmented cladding fiber by bicomponent spinning method was proposed. The polymer segmented cladding fiber with required cross section was successfully fabricated using polycarbonate (PC) and polymethyl methacrylate (PMMA). The core of obtained fiber is 40 μm in diameter. The output spectrum of obtained fiber was investigated using white light as the light source. From the output spectra, it was seen that the intensity in the wavelength of 730～830 nm is comparatively higher in the test range of 500～1000 nm. The transmission loss in the wavelength of 500～1000 nm was tested by the cut-back method. The result showed that the transmission loss of the obtained fiber is comparatively high, being up to 30 dB/m. The output light pattern of the obtained fiber of 60 cm was collected by a CCD camera with laser light of 532 nm as the input.
