“…Considering these tight tolerances, "lters based on single defects will not be fabricated in the foreseeable future. The experimental demonstrations of such "lters that we have seen already [30,32,42] underline this point, because the target wavelength was missed by 10 nm or more [30,32] and it was shown what a large tuning range can be achieved with a small change in cavity size [42].…”

During the last decade, photonic crystals, also known as photonic microstructures or photonic bandgap structures, have matured from an intellectual curiosity concerning electromagnetic waves to a "eld with real applications in both the microwave and optical regime. In this review, we shall focus on progress and the prospects for semiconductor structures that mainly involve guided modes interacting with periodic structures, but we also evaluate alternative material systems and fabrication methods, e.g. those based on self-organisation. We shall go from basic concepts, via a discussion of the state of the art, to device applications. Naturally, the discussion of the applications will be more speculative, but we attempt to evaluate the real prospects o!ered by photonic crystals at optical frequencies while considering practical limitations. In doing so, we identify a variety of areas such as the combination of quantum dot light emitters with photonic crystals that seem particularly promising. We discuss the prospects for enhanced light}matter interactions in photonic crystals and the related material and design issues. Overall, the aim of this review is to introduce the reader to the concepts of photonic crystals, describe the state of the art and attempt to answer the question of what uses these peculiar structures may have.

“…This type of localized mode can exhibit a high cavity Q and a small modal volume, making the structure ideal for the waveguide of a microcavity laser. forming defect states in the forbidden gaps between leaky-mode bands [16], [27]. Such photon states are less localized than the guided-mode defect states and, due to radiation losses, exhibit a lower cavity Q.…”

C oupled vertical cavity surface-emitting laser (VCSEL) arrays are an attractive means to increase the coherent output power of VCSELs. Single-mode VCSELs, with output powers greater than 10 mW, would be useful as telecommunication transmitters (λ=1.3-1.55 µm) or sources for optical interconnects. Commercially available single-mode VCSELs, even at shorter wavelengths (λ=0.85 µm), are generally limited to a few milliwatts of output power. The conventional VCSEL structure incorporates a built-in positive-index waveguide, designed to support a single fundamental mode. Promising results in the 3-5 mW range (λ=0.85 µm) have been obtained from wet-oxidized, positive-index-guided VCSELs [1], [2] with small emission apertures (less than 3.5 µm-dia). The small aperture size leads to a high electrical resistance and high current density, which can impact device reliability.A larger emitting aperture is essential to reduce thermal rollover and achieve higher output powers with reliable operation. However, poor intermodal discrimination, gain-spatial-hole burning, and thermally induced self-focusing prevent single-mode outputs from larger aperture devices. Furthermore, to minimize nonlinear above-threshold effects, a relatively large built-in index step is desirable for mode stability in active devices. Unfortunately, positive-index-guided structures posses an inherent tradeoff between aperture size and index step, due to the modal cutoff conditions for single-mode operation.By contrast, antiguided VCSEL structures have shown promise for achieving larger aperture single-mode operation. To obtain high single-mode powers with a larger emitting aperture, the use of a negative-index guide (antiguide) is beneficial.

This review article is concerned with basic aspects and some selected topics in photonic crystal (PhC) devices. It starts with a significantly historical aspect of basic principles for photonic crystals that it is hoped will help the reader to develop a critical appreciation of the research literature. It continues by describing topics such as PhC beamsplitters, slow‐light structures, micro‐/nanoresonators, coupled resonator optical waveguides (CROWs) and PhC‐based semiconductor lasers. Emphasis is placed on both the conceptual and the practical matters that need to be addressed in order to fulfill the tasks of designing and realizing devices that exploit photonic crystal principles. The review also addresses some of the problems encountered in the fabrication of photonic crystal devices using the planar technologies of integrated photonics, which are those that are most likely to be used in future commercial production.
