Highly birefringent index-guiding photonic crystal fibers

Abstract

Abstract-Photonic crystal fibers (PCFs) offer new possibilities of realizing highly birefringent fibers due to a higher intrinsic index contrast compared to conventional fibers. In this letter, we analyze theoretically the levels of birefringence that can be expected using relatively simple PCF designs. While extremely high degrees of birefringence may be obtained for the fibers, we demonstrate that careful design with respect to multimode behavior must be performed. We further discuss the cutoff properties of birefringent PCFs and present experimental results in agreement with theoretical predictions on both single-and multimode behavior and on levels of birefringence.

Alcohol sensing over O+E+S+C+L+U transmission band based on porous cored octagonal photonic crystal fiber

“…Some identical properties are seen like as nonlinearity [1,2], high birefringence [3,4], high sensitivity [5,6], low confinement loss [7,8], improved effective area, and endlessly single mode [9][10][11]. For these reasons, PCF has drawn a great attraction among researchers.…”

“…As an optical medium, photonic crystal has some identical properties [1][2][3][4][5][6][7][8][9][10][11]. The photonic crystal fibers are enormously used in the optical fiber technology due to its idiosyncratic properties.…”

Highly Birefringent and Dispersion Compensating Photonic Crystal Fiber Based on Double Line Defect Core

“…Since the refractive index contrast between the core and the cladding in PCF is higher than that of conventional optical fiber, high birefringence can be easily realized in PCFs. So far, various highly birefringent PCFs (HB-PCFs) have been reported by breaking the symmetry of the fiber core or cladding [12,15,[18][19][20][21][22][23][24][25]. The birefringence of these HB-PCFs ranges from 10 -3 to 10…”

Photonic liquid crystal fiber intermodal interferometer

“…PCFs may feature solid core guiding by modified Total Internal Reflection (mTIR) or hollow core, whose guiding mechanism is by Photonic BandGap (PBG) transmitting only certain wavelengths values [1][2][3]. Some sorts of PCFs have several cores or holes of different diameters in order to improve specific properties as endlessly modes or polarization maintaining [4,5]. These properties may be further boost by infiltrating in the holes a birefringent medium such a liquid crystal.…”
