We theoretically investigate the thermally tunable photonic crystal fiber (PCF) coupler infiltrated with nematic liquid crystals. The thermo-optical responsive NLC offers thermal tunability of the fiber coupler. The proposed design can find promising sensor applications.
We propose a nested photonic crystal cavity configuration for on-chip wavelength conversion based on adiabatic tuning of the resonator whereby dynamic switching between two cavity structures significantly extends the achievable frequency conversion range.
2009 marks ten years since the first report of supercontinuum generation in photonic crystal fiber. These results have had wide-reaching impact, and continue to stimulate new research directions in nonlinear dynamics and nonlinear optics.
Second harmonic (SH) nonlinear diffraction including Cerenkov SH radiation and generation of conical and toroidal SH waves in 1D and 2D nonlinear photonic structures with modulation of the sign of quadratic nonlinearity are reported.
