“…During the polishing process, the remaining length of the cladding region is determined by measuring a scattering loss due to scattering on the surface. 11 As the remaining length of cladding region is reduced, the evanescent field coupling on the surface of D-shaped fiber is enhanced and the scattering loss is increased. For the interaction length of 4 cm, three samples A, B, and C with different scattering losses, such as 1, 4, and 7 dB, were fabricated, which were resulted in different remaining lengths of cladding region, such as 13.5, 9.5, and 6.5 m, respectively.…”

The effect of single-wall carbon nanotubes (SWNTs) on nonlinear optical absorption of D-shaped fibers with versatile the remaining length of the cladding region and the interaction length are investigated. The optical absorption based on SWNTs is induced by the energy bandgap in SWNTs. The bandgap energy depends on the tube diameter of SWNTs. After fabricating versatile D-shaped fiber, SWNTs are deposited on the polished surface of D-shaped fibers. The cladding region of single mode fibers is removed by a side-polishing technique and the D-shaped fiber is obtained. In the D-shaped fiber, the cladding region is thin enough to induce the evanescent field coupling of core mode to the other modes of the SWNT-overlay. The nonlinear absorption based on the SWNTs-overlay is changed by the remaining length of cladding region and the interaction length because the coupling strength of evanescent field strongly depends on the different remaining lengths of the cladding region and the interaction lengths as well.

“…[2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] In recent years, D-shaped PCFs have attracted great research interest because they allow broadband operation in their specific applications. [17][18][19][20][21] Typically, the D-shaped optical fiber has been fabricated by burying a fiber in a grooved quartz block and then grinding the cladding to a thickness of a few microns, causing a range of materials overlaid on the polished cladding window to interact with an evanescent field of light propagating through the core. When a PCF with C 6v symmetry is processed, its crystallographic axes must be considered because the symmetry is broken once the PCF is ground.…”

We present a method for determining crystallographic symmetry axes in an air-hole structure of a photonic crystal fiber (PCF) with a hexagonal structure. This method is based on the measurement of intensity distribution of the light transversely scattered from the PCF. The symmetry axes can be determined from the distinctive intensity pattern that is repeated for an axial rotation of the PCF. Simulations and experimental studies reveal that the technique is reliable and quite sensitive to the angle between the crystallographic symmetry axis and the launched light.
