“…Even though straightforward application of the photonic bandgap (PBG) concept is generally thought to require a three-dimensional PC [1][2][3][4], the largest interest so far is attracted by two-dimensional PCs because they are potentially more amenable to fabrication and much closer to application [5]. However, definite standardization is still far from being achieved and different fabrication methods [6][7][8], architectures and integration strategies [9][10][11] of two-dimensional PCs are under investigation and in competition to produce the first target to market devices.…”

Two-dimensional photonic crystals have been fabricated by x-ray lithography and reactive ion etching on an air/GaAs/AlGaAs asymmetric waveguide. The shape of the lattice unit cell has been varied by exploiting x-ray diffraction effects and nonlinear response of resists during the development process. Rings with or without a central pillar have been fabricated with a resolution down to 50 nm. Lithographic details are described to show the accuracy of this fabrication technique. Optical characterization has been performed showing the presence of a well defined photonic band structure as well as band anti-crossing. The results are discussed and compared with theoretical calculations of the photonic band dispersion. Structures with high dielectric fraction are shown to yield photonic modes with small line widths and low propagation losses. The reliability and the precise control of the fabricated sample structures make this lithographic method useful for a full investigation of optical properties on the dependence of the lattice unit cell shape.

This paper describes the InP platforms for photonic integration and the development on these platforms of an optical code division multiple access (O-CDMA) system for local area networks. We demonstrate three building blocks of this system: an optical pulse source, an encoder/decoder pair, and a threshold detector. The optical pulse source consists of an integrated colliding pulse-mode laser with nearly transform-limited 10 Gb/s pulses and optical injection locking to an external clock for synchronization. The encoder/decoder pair is based on arrayed waveguide gratings. Bit-error-rate measurements involving six users at 10 Gb/s showed error-free transmission, while O-CDMA codes were calibrated using frequency resolved optical gating. For threshold detection after the decoder, we compared two Mach-Zehnder interferometer (MZI)-based optical thresholding schemes and present results on a new type of electroabsorber-based MZI.

“…Most of these applications depend on the existence of an absolute photonic band gap (PBG), which means all of the light's beam cannot propagate along all possible directions in the structure. As we all know, a large PBG is the corner stone of various applications such as optical mirrors [8], filters [9], and switches [10], etc. Since the threedimensional (3D) PCs can control the spread of the light beam in any direc tion, they become the most desirable optical device.…”

Twodimensional photonic crystal (PC) slabs exhibiting photonic band gaps (PBGs) in both TE and TM polarizations are of particular interest for a better control of light propagation and easy experimental fabrication. Through reducing the symmetry of the PC lattice, simultaneous realization of PBGs in both TE and TM polarizations within a certain frequency region can be achieved. Based on the air holes immersed in the silicon background, two kinds of two dimensional PC slab structures are proposed. These are a honeycomb lattice of circular air holes with different sizes and larger circles, and smaller triangles alternately arranged, respectively. The light transmittances show that these two structures offer large complete band gaps. Different kinds of straight waveguides are designed, and their abilities of localizing the incident beam are studied by analysing the light transmittances and spatial field distributions, where the light energy is localized perfectly in the optimized waveguide structure. Our proposed PC slab waveguides are convenient for fabrication, and could be applied in future alloptical integrated circuits.
