Dispersion Characteristic Calculation of Photonic Crystal Fiber Guided Modes

Dispersion characteristic of photonic crystal fiber guided mode is calculated. Numerical modeling based on the Maxwell equation for magnetic components for field of the photonic crystal is obtained. It is shown, that slot photonics crystal waveguides can be used to tailor dispersion.

The Perspective Slow-wave Systems of Terahertz Band for TWT

In this paper the review of terahertz perspective slow-wave systems is presented for TWT. The methods of modeling have been considered and some numerical results are presented.

Parametric Gain Calculation in Photonic Crystal Fiber

Signal wave parametric gain was calculated in photonic crystal optical fiber. Photonic crystal fiber structure was optimized for broadband parametric gain. It is shown, that gain bandwidth for photonic-crystal fiber optical parametric amplifier could be more than 400 nm. Spectral changings in parametric gain due to modulation of photonic crystal waveguide cross-section was studied.
