Photonic crystal power dividers using L-shaped bend based on ring resonators
Mehrdad Djavid, Afshin Ghaffari, Faraz Monifi, Mohammad Sadegh Abrishamian
We propose a new type of two-dimensional photonic crystal power dividers based on ring resonators and directional couplers that can be applicable to photonic integrated circuits. The proposed power divider's mechanism is analogous to that of conventional waveguide directional couplers, ... [J. Opt. Soc. Am. B 25, 1231-1235 (2008)]

Ultraslow light pulses in a nonlinear metamaterial
Giuseppe D'Aguanno, Nadia Mattiucci, Mark J. Bloemer
We find the analytical expression for the threshold intensity necessary to launch ultraslow light pulses in a metamaterial with simultaneous cubic electric and magnetic nonlinearity. The roles played by the permittivity, the permeability, the electric cubic nonlinearity, the magnetic cubic ... [J. Opt. Soc. Am. B 25, 1236-1241 (2008)]

Measurement of the temporal coherence in broadband sources using the radio-frequency transfer function of a dispersive system
Carlos R. Fern?ez-Pousa, Haroldo Maestre, Adri?J. Torregrosa, Juan Capmany
We present a noninterferometric method for direct and complete characterization of the degree of first-order temporal coherence ?(?) of low-coherence broadband sources both in amplitude and phase. The method is based on measuring the radio-frequency transfer function H_RF(f) of ... [J. Opt. Soc. Am. B 25, 1242-1253 (2008)]
