Supercontinuum Source for Dense Wavelength Division Multiplexing in Square Photonic Crystal Fiber via Fluidic Infiltration Approach

Abstract

In this paper, a square-lattice photonic crystal fiber based on optofluidic infiltration technique is proposed for supercontinuum generation. Using this approach, without nano-scale variation in the geometry of the photonic crystal fiber, ultra-flattened near zero dispersion centered about 1500 nm will be achieved. By choosing the suitable refractive index of the liquid to infiltrate into the air-holes of the fiber, the supercontinuum will be generated for 50 fs input optical pulse of 1550 nm central wavelength with 20 kW peak power. We numerically demonstrate that this approach allows one to obtain more than two-octave spanning of supercontinuum from 800 to 2000 nm. The spectral slicing of this spectrum has also been proposed as a simple way to create multi-wavelength optical sources for dense wavelength division multiplexing.

Supercontinuum Generation Assisted by Wave Trapping in Dispersion-Managed Integrated Silicon Waveguides

“…Since then, it has been observed in a wide variety of bulk nonlinear media [4][5][6][7][8] and various types of waveguides [9][10][11]. Today, broadband SC generation has found numerous applications, such as high-precision spectroscopy [12][13][14], frequency metrology and synthesis [15][16][17], ultrashort-pulse generation [18], wavelengthdivision-multiplexing (WDM) communication [19], and nonlinear optical spectroscopy and imaging in biophotonics [20][21][22]. The integration of SC sources on a chip, based on compact planar waveguide circuits rather than optical * simon.pierre.gorza@ulb.be fibers, can provide compact, robust, and power-efficient platforms for the aforementioned applications.…”

“…Thus, waveguides in a PhC can be created by removing one or more rows of dielectric rods. PhC-based structures are excellent choices for designing many types of optical devices such as optical filters [3][4][5][6][7][8], PhC fibers [9][10][11][12][13][14][15][16][17][18], multiplexers and demultiplexers [19][20][21][22][23][24][25][26], encoders and decoders [27][28][29][30], switches [31][32][33][34][35][36], logic gates [37][38][39][40][41][42], analog to digital converters (ADCs) [43][44][45][46][47][48][49], and sensors [50]…”
