Paper Abstract

Transmission and reflection of ultrashort (100 fs - 100 ps) transform-limited Gaussian light pulses through/from biharmonic Bragg grating with sinusoidally - modulated amplitude and periodically located phase shifts ? is considered theoretically using numerical simulations. The method of investigation comprises coupled-wave theory and spectral approach. The effect of input pulse duration upon the shape of transmitted and reflected pulses is examined. It is shown that 100 Ps input pulses are transmitted through biharmonic grating without distortions if centered at Bragg wavelength (inside grating passband) and are reflected from the grating without distortions if centered at wavelengths inside the stopband. The results of this study indicate that biharmonic gratings can find application for demultiplexing and multiplexing optical signals in multichannel high-bit-rate fiber communication networks with bit rates up to 10 Gbits/s per channel.
