Dynamics of counterpropagating pulses in photonic crystals: enhancement and suppression of stimulated emission processes.
Marco Centini,Giuseppe D'Aguanno,Michael Scalora,M. J. Bloemer,Charles M. Bowden,Concita Sibilia,Nadia Mattiucci,Mario Bertolotti +7 more
TL;DR: Using numerical methods, it is shown that linear interference and localization effects combine to either enhance or suppress stimulated emission processes, depending on the initial phase difference between the input pulses.
Transit time of chirped pulses through one-dimensional, nonabsorbing barriers
Giuseppe D'Aguanno,Marco Centini,Mark J. Bloemer,Krishna Myneni,Michael Scalora,Charles M. Bowden,Concita Sibilia,Mario Bertolotti +7 more
TL;DR: A generalization of the transit time for chirped pulses is proposed that is still meaningful even when the transit times are superluminal or negative, and whose predictions agree well with the experimental results.
Enhanced second harmonic generation from resonant GaAs gratings
TL;DR: This work theoretically study second harmonic generation in nonlinear, GaAs gratings and predicts second-harmonic conversion efficiencies approximately 5 orders of magnitude larger than conversion rates achievable in either bulk or etalon structures of the same material.
Long range plasmon assisted all-optical switching at telecommunication wavelengths
TL;DR: The properties of ultranarrow, Fano-like resonances generated by the coupling of long range surface plasmons with ultrathin, metallic, subwavelength gratings embedded in a nonlinear, cubic material are exploited to obtain all-optical switching at telecommunication wavelengths for extremely low input power.
Dispersive properties of one-dimensional photonic band gap structures for second harmonic generation
Marco Centini,Michael Scalora,Concetta Sibilia,Giuseppe D'Aguanno,Mario Bertolotti,Mark J. Bloemer,Charles M. Bowden +6 more
TL;DR: In this article, the dispersive properties of one-dimensional photonic band gap structures were analyzed, and applications to phase matching conditions in the case of second harmonic generation were discussed.
