我们描述了一个准二维（2-D）光学系统的实验，包括一个三角形阵列的气缸蚀刻通过激光类Ga（Al）As波导异质结构。这种结构可以很好地近似于无限大二维光子晶体。我们首先给出了一组光学性质的测量结果（透射、反射和衍射），包括在两个这样的晶体之间形成的面内法布里-珀罗腔的情况，该测量方法利用嵌入式量子威尔斯或InAs量子点的引导光致发光来产生内部探测光束。在第二部分中，面内微米大小的光子盒界定的圆形沟槽或二维光子晶体内的激发自发辐射探测，在这样的光子盒中观察到的高品质因数证明了在这些系统中可实现的优异的光子约束，并允许访问模式结构的细节。最后，提出了一些应用前景。
We describe experiments on a quasi-two-dimensional (2-D) optical system consisting of a triangular array of air cylinders etched through a laser-like Ga(Al)As waveguiding heterostructure. Such a configuration is shown to yield results very well approximated by the infinite 2-D photonic crystal (PC), We first present a set of measurements of the optical properties (transmission, reflection, and diffraction) of slabs of these photonic crystals, including the case of in-plane Fabry-Perot cavities formed between two such crystals, The measurement method makes use of the guided photoluminescence of embedded quantum wells or InAs quantum dots to generate an internal probe beam. Out-of-plane scattering losses are evaluated by various means, In a second part, in-plane micrometer-sized photonic boxes bounded by circular trenches or by two-dimensional photonic crystal are probed by exciting spontaneous emission inside them, The high quality factors observed in such photon boxes demonstrate the excellent photon confinement attainable in these systems and allow to access the detail of the modal structure. Last, some perspectives for applications are offered.
