Lower bound for the spatial extent of localized modes in photonic-crystal waveguides with small random imperfections
Light localization due to random imperfections in periodic media is paramount in photonics research. The group index is known to be a key parameter for localization near photonic band edges, since small group velocities reinforce light interaction with imperfections. Here, we show that the size of the smallest localized mode that is formed at the band edge of a one-dimensional periodic medium i...
متن کاملNonlinear Localized Modes In Photonic Crystal Waveguides
E xamples of the most significant recent research in optics and engineering are published each year in the December issue of OPN. This issue is comprised of short descriptions of the "hottest" topics in current optics research. Selection criteria applied to submissions are as follows: • the accomplishments described must have been published in a refereed journal in the year prior to publication...
متن کاملModes of coupled photonic crystal waveguides.
We consider the modes of coupled photonic crystal waveguides. We find that the fundamental modes of these structures can be either even or odd, in contrast with the behavior in coupled conventional waveguides, in which the fundamental mode is always even. We explain this finding using an asymptotic model that is valid for long wavelengths.
متن کاملStatistical measurements of quantum emitters coupled to Anderson-localized modes in disordered photonic-crystal waveguides.
We present a statistical study of the Purcell enhancement of the light emission from quantum dots coupled to Anderson-localized cavities formed in disordered photonic-crystal waveguides. We measure the time-resolved light emission from both single quantum emitters coupled to Anderson-localized cavities and directly from the cavities that are fed by multiple quantum dots. Strongly inhibited and ...
متن کاملBloch modes and self-localized waveguides in nonlinear photonic crystals
We present a modeling technique that uses eigenmode expansion to simulate infinite periodic structures with Kerr nonlinearity. Using a unit cell with Bloch boundary conditions, our iterative algorithm efficiently calculates self-consistent two-dimensional Bloch modes. We show how it can be used to study the band structure of nonlinear photonic crystals and to gain rapid insight in the operation...
