… This kind of artificial material was named by Yablonovitch and John as a photonic crystal in
… of a photonic crystal is that it has photonic gaps. Light with frequencies located in the gaps …

… crystal slab. The truncation of outer layers determine the position of the modes inside the band
gaps … and becomes infinite at the edge of band gaps. In this way, the total thickness of the …

… of the photonic crystal. The … photonic crystal while the defect mode frequency is independent
of it. This method is useful for photonic band gap engineering and designing the photonic-…

… 1a we show the dispersion of photonic modes in a membrane photonic crystal with air …
Solid (dashed) lines represent the edges of photonic gaps for modes which are even (odd) …

… To illustrate this point, we remove a row of dielectric rods from the photonic crystal described
above. This has the effect of introducing a single guided-mode band inside the gap. The …

… spectra and calculated gap modes suggests that coupling between surface modes and core
… to get band gaps for every propagation direction and each polarization in a photonic crystal. …

… modes can occur within the forbidden band gap. Addition of extra dielectricmaterial locally,
inside the photonic crystal, produces "donor" modes… of our photonic crystal cutting through the …

… of the properties of photonic crystals for the control of optical spatial structures has been
considered 13–15. In 13 we showed how the photonic band gap of a photonic crystal could be …

… fictitious, auxiliary longitudinal modes. Our strategy also … gap of three-dimensional photonic
crystals. Exploiting this, we systematically study the topology of the minimal fundamental gaps…

… Although they can not possess true optical band gaps, 2D photonic crystal structures etched
into semiconductor waveguides are also of substantial interest, due in part to the relative …
