We start with an overview of what photonic crystals are and the basic principles behind their operation. We go on to discuss the design of the first photonic crystals in the microwave regime and their fabrication. We will then go on to look at photonic crystals in the optical regime their fabrication and their applications, including LEDs, lasers, reflectors, waveguides and circuits. Introduction and Basic Principles Photonic crystals offer an exciting new way to control the propagation of light. They promise many great applications, such as high efficiency light sources, low threshold lasers and waveguides into which we can introduce sharp bends. Photonic crystals are to photons, what semiconductors are to electrons, and it is hoped that they will offer as many applications. A photonic crystal is a dielectric containing a periodic arrangement of gaps of another material with a different refractive index. If the refractive index contrast is sufficiently high a band gap forms. This band gap is a set of photon energies which are forbidden from propagating in the material. As the wavelength of electromagnetic radiation is directly related to the photon energy by the equation λ = hc/E, we can say that the crystal blocks radiation of certain wavelengths. These wavelengths are of the order of the distance between gaps in the structure. The reason why this happens is similar to the reason for the existence of a bandgap in a semiconductor. A semiconductor consists of freely propagating electrons in a periodically varying electric field (due to the ions). A photonic crystal consists of photons propagating in periodically varying dielectric constant. One important thing to note is the effect that the crystal has on the emission of photons with energies inside the photonic bandgap in the material. These photons are not emitted and reabsorbed b h bl f h i i hi h h i i i i f bidd One other common feature of photonic crystals and semiconductors is the ability to introduce defect modes into the crystal. By breaking the periodicity of the crystal, either by adding or removing parts of the lattice, we can create energies inside the band gap at which photons are permitted to propagate. This is equivalent to the doping of semiconductors in order to create energy levels inside the semiconductor bandgap. Yablonovite The first photonic crystals were fabricated with a bandgap in the microwave region of the spectrum. This is because the long wavelength of microwaves means that the photonic structure is large enough to be machined. These crystals were produced in 1989 by Eli Yablonovitch at Bell Communications Research in New Jersey. [2, E. Yablonovitch et al, 1989] They machined a number of these crystals by drilling holes in a number of different dielectric materials with a range of dielectric constants. The holes were drilled in a face-centred-cubic arrangement because the theory suggested that this was the simplest structure that was likely to give the desired bandga

我们首先概述光子晶体是什么以及它们运作背后的基本原理。我们接着讨论了在微波环境下第一个光子晶体的设计和制造。然后，我们将继续研究光子晶体在光学系统中的制造和应用，包括led，激光器，反射器，波导和电路。光子晶体为控制光的传播提供了一种令人兴奋的新方法。它们承诺了许多伟大的应用，如高效光源，低阈值激光器和波导，我们可以引入尖锐的弯曲。光子晶体之于光子，就像半导体之于电子一样，人们希望它们能提供同样多的应用。光子晶体是一种介电体，其中包含具有不同折射率的另一种材料的周期性间隙排列。如果折射率对比度足够高，就会形成带隙。这个带隙是一组被禁止在材料中传播的光子能量。由于电磁辐射的波长与光子能量由λ = hc/E方程直接相关，我们可以说晶体阻挡了某些波长的辐射。这些波长与结构中间隙之间的距离成数量级。发生这种情况的原因类似于半导体中存在带隙的原因。半导体由在周期性变化的电场(由于离子)中自由传播的电子组成。光子晶体由以周期性变化的介电常数传播的光子组成。需要注意的一件重要的事情是晶体对光子发射的影响，光子发射的能量在材料的光子带隙内。这些光子不会被发射和重吸收，光子晶体和半导体的另一个共同特征是能够在晶体中引入缺陷模式。通过增加或移除部分晶格，打破晶体的周期性，我们可以在带隙内创造能量，光子可以在带隙内传播。这相当于为了在半导体带隙内产生能级而掺杂半导体。在光谱的微波区制备了具有带隙的第一个光子晶体。这是因为微波的波长长意味着光子结构足够大，可以进行加工。这些晶体是1989年由新泽西州贝尔通信研究所的Eli Yablonovitch制造的。[2, E. Yablonovitch等人，1989]他们通过在介电常数范围内的不同介电材料上钻孔来加工出许多这样的晶体。这些孔被钻成面心立方的排列，因为理论表明，这是最简单的结构，可能在所有方向的传播中提供所需的带隙。最终显示出完整的三维带隙的材料的微波折射率为3.5。钻出的孔足够大，它们重叠，86%的材料被钻掉。这项工作首次成功地证明了光子带隙实际上是可以被创造出来的。然而，光子晶体在光学体制的发展相当困难。
