“…So far, photonic crystal lasers have been demonstrated in both the InGaAsP/InP and InGaAs/GaAs quantum well material systems, emitting in the 1.5 m telecommunication wavelength range 9,10 and at 930 nm. 11 However, when using quantum well material, this geometry suffers from significant reabsorption of light in the lithographically defined mirrors, since both the active light-emitting region in the cavity as well as the photonic crystal mirrors absorb light. Nonetheless, we find that two-dimensional ͑2D͒ photonic crystal slab defect cavities can be easily fabricated by using planar lithography and etching technologies and offer desired high Q's and small mode volumes.…”

We have characterized the modes within two-dimensional photonic crystal nanocavities with self-organized indium arsenide quantum dots as an active material. Highly localized donor mode resonances with 3 to 5 nm linewidth were observed when spatially selective optical pumping the cavities. These modes could be lithographically tuned from 1100 to 1300 nm. Other, more extended modes, were also characterized and exhibited narrower resonance linewidths ranging from 0.6 to 2 nm.

“…DBR-free PCSEL with optical pumping from a microcavity formed by a single defect in the center of a 2D air column photonic crystal based membrane slab waveguide structure has been demonstrated and reported in Science [16], which was the first experimental proof of surface emitting lasing due to photonic crystal cavity and spontaneous emission control [16,17]. Shortly after, an electrically injected PCSEL was proposed and demonstrated ( Figure 1a) by the author and co-workers [18,19], which was the first experimental Significant progresses have been made since then, with various configurations have been proposed and demonstrated [20][21][22][23][24][25][26][27][28][29][30][31][32], including electrically injected photonic crystal quantum cascade surface emitting lasers (QCLs) [26], VCSEL pumped PCSELs [23], and improved electrical injection structures [28]. Additionally, due to the nature of scalability, PCSELs have been demonstrated on different material systems, from GaN (UV) to GaAs (1µm) to InP (1.5µm) and QCL IR (8µm) lasers systems [26,27].…”

We propose and report a novel photonic crystal (PhC) encapsulation concept, where the originally exposed air holes are sealed off on top of the surface to create an enclosed air column structure in two dimensional (2D) PhC based devices and systems. The impact of encapsulation on the photonic bandgap will be discussed for different encapsulation conditions. Experimental results on encapsulation process will also be reported, with focus on the nanoparticle based self assembly encapsulation. Finally a novel photonic crystal surface emitting laser based on this encapsulation concept will be proposed and discussed. The surface state induced non-radiative recombination and different electrical injection schemes will be discussion with the benefit of encapsulation being discussed in the end.

“…While these requirements are not easy to realize for optically pumped photonic crystal lasers, they become even more challenging in the presence of semiconductor carrier injection structures. Electroluminescence from a photonic crystal defect structure was observed in 2000 [78,79]. The active layer of the device was a pair of 7 nm In 0.15 Ga 0.…”

We review basic physics of photonic crystals, discuss the relevant fabrication techniques, and summarize important device development in the past two decades. First, photonic band structures of photonic crystals and the origin of the photonic band gap are analyzed. Fundamental photonic crystal structures, such as surfaces, slabs, and engineered defects that include cavities and waveguides, are examined. Applications at visible and infrared wavelengths require photonic crystals to have submicron features, sometimes with precision down to the nanoscale. Common fabrication methods that have helped make such exquisite structures will be reviewed. Lastly, we give a concise account of key advances in photonic crystal-based lasers, light-emitting devices, modulators, optical filters, superprism-based demultiplexers and sensors, and negative index materials. Electron-beam nanolithography has enabled major research progress on photonic crystal devices in the last decade, leading to significant reduction of size and/or power dissipation in devices such as lasers and modulators. With deep ultraviolet (DUV) lithography, these devices may one day be manufactured with the prevalent CMOS technology at affordable cost.
