Dispersionless tunneling of slow light in antisymmetric photonic crystal couplers

Ha Sangwoo; Sukhorukov Andrey; Dossou Kokou; Botten Lindsay; Lavrinenko Andrei; Chigrin Dmitry; Kivshar Yuri (Optical Society of America, 2008)

We suggest a novel and general approach to the design of photonic-crystal directional couplers operating in the slow-light regime. We predict, based on a general symmetry analysis, that robust tunneling of slow-light pulses ...
A Newton-GMRES Approach for the Analysis of the Postbuckling Behavior of the Solutions of the von Karman Equations

Dossou Kokou; Pierre Roger (SIAM (Society for Industrial & Applied Mathematics) Journals, 2003)

We propose a Newton-GMRES¿type algorithm to solve the discrete von Karman problem. We show that this algorithm is efficient both in memory andcomputation time and robust in the neighborhood of the singular points of the ...
UV-induced modification of stress distribution in optical fibers and its contribution to bragg grating birefringence

Belhadj Nezih; Park Yongwoo; Larochelle Sophie; Dossou Kokou; Azana Jose (Optical Society of America, 2008)

This paper discusses the importance of stress-induced contributions to the photo-induced birefringence observed in fiber Bragg gratings. Optical tomography measurements are performed in exposed and unexposed fibers to ...
