“…Highly birefringent PCFs have possibilities of realizing a single-polarization single-mode (SPSM) fiber [68], [69], which guides only one polarization state of the fundamental mode. The SPSM fiber can eliminate both polarization mode coupling and polarization mode dispersion.…”

Abstract-Recent progress on numerical modeling methods for photonic crystal fibers (PCFs) such as the effective index approach, basis-function expansion approach, and numerical approach is described. An index-guiding PCF with an array of air holes surrounding the silica core region has special characteristics compared with conventional single-mode fibers (SMFs). Using a full modal vector model, the fundamental characteristics of PCFs such as cutoff wavelength, confinement loss, modal birefringence, and chromatic dispersion are numerically investigated.Index Terms-Finite-element method, holey fiber, microstructured optical fiber, numerical modeling, photonic band-gap fiber, photonic crystal fiber.

Abstract-In this paper, we demonstrate a new & simple rectangular photonic crystal fiber (RPCF) for high negative dispersion covering the E to U communication band with ultra-high birefringence, large nonlinearity. According to the simulation results, the designed fiber shows negative dispersion coefficient of -776 to -1591 ps/(nm.km) over E to L communication bands with the relative dispersion slope (RDS) is perfectly matched to that of a single mode fiber. In addition, the proposed RPCF offers a high value of birefringence 2.97×10-2 and a large nonlinear coefficient of 44.5W-1km-1, both at the operating wavelength of 1550 nm. Moreover, the proposed RPCF achieved two zero-dispersion wavelengths in the visible and near IR regions for both of the x and y polarization modes.Index Terms-Photonic crystal fiber, negative dispersion, high birefringence, rectangular lattice.

“…Hydrostatic pressure sensors based on birefringent fibers are not compact since they usually need non-fiber components to detect the pressure-induced phase or use the fiber Sagnac interferometer with a relatively long sensing fiber. PCFs [28][29][30][31][32] are the great success in the history of optical fibers, which have achieved excellent properties in birefringence [33][34][35][36][37][38][39][40], dispersion [41][42][43][44][45][46][47][48][49][50][51], single polarization single mode [52][53][54], nonlinearity [55], and effective mode area [56][57][58], and also excellent performances in the applications of fiber lasers [59][60][61] and nonlinear optics [62][63][64][65] over the past several years. PCFs have also further improved optical fiber sensors and have been used for strain sensing [66], gas sensing [67], biochemical sensing [68], refractive index sensing [69] and temperature sensing [70].…”

Abstract-A novel hydrostatic pressure sensor based on a gold-coated fiber modal interferometer (FMI) is proposed and demonstrated. Two single mode fibers (SMFs) are spliced with a lateral offset which forms a single-end FMI. The single-end FMI is gold-coated to enhance the reflectivity and to avoid the influence of any unwanted light from getting into the sensor. Relative reflection spectra of the proposed FMIs with different sensing SMF lengths or different lateral offsets are experimentally investigated. A high hydrostatic pressure sensor test system is proposed for the testing of the proposed FMI pressure sensor. The performance of a gold-coated FMI pressure sensor based on a 12-mm sensing SMF has been experimentally investigated. The proposed pressure sensor has a sensing range from 0 to 42 MPa and a sensitivity of 53 pm/MPa.
