Abstract

In recent years, the generation of few cycle pulses has been of great scientific and technological interest. In this line, the microstructured optical fibers have been playing a vital role since the desired optical properties can easily be engineered by adjusting the geometrical parameters. The recent results reveal that the quasicrystals exhibit several interesting photonic properties over periodic crystals. A solid core photonic quasi-crystal fiber (SC-PQF) is a novel microstructured fiber with quasi periodicity in structure and has a long range order with aperiodic arrangement in its cladding region. The structure of the cladding region consists of air holes of diameter d and pitch, Λ, with five rings of air holes. In the central region, the air hole is removed and the resulting solid silica core acts as a defect and gives rise to the propagation of guided modes. The photonic quasi-crystal fiber provides very large nonlinearity and sufficiently low dispersion that could be exploited for generating single cycle pulses. We look for the hitherto mentioned optical properties in the proposed SC-PQF by carefully optimizing the geometrical parameters namely, core diameter and the pitch. Eventually, with the proposed fiber, we study both dispersion and nonlinearity for a range of wavelengths from 0.6 to 1.1 μm and demonstrate sufficiently low dispersion (-1.9478 ps2/m) with zero confinement loss and enhanced nonlinearity (γ = 578 W-1m -1) for a wavelength of 0.85 μm. The soliton effect compression of the femtosecond pulses in the proposed SC-PQF at 0.85 μm wavelength is numerically studied. A 15 fs pulse compressed down to 4 fs results in nearly 1.4 cycles of pulse generation.
