摘要： Structures and methods for forming highly uniform and high-porosity gallium-nitride layers with sub-100-nm pore sizes are described. Electrochemical etching of heavily-doped gallium nitride at low bias voltages in concentrated nitric acid is used to form the porous gallium nitride. The porous layers may be used in reflective structures for integrated optical devices such as VCSELs and LEDs.

摘要： Various embodiments of the present invention are related to microresonator systems that can be used as a laser, a modulator, and a photodetector and to methods for fabricating the microresonator systems. In one embodiment, a microresonator system (100) comprises a substrate (106) having a top surface layer (104), at least one waveguide (114,116) embedded within the substrate (106), and a microdisk (102) having a top layer (118), an intermediate layer (122), a bottom layer (120), current isolation region (128), and a peripheral annular region (124,126). The bottom layer (120) of the microdisk (102) is in electrical communication with the top surface layer (104) of the substrate (106) and is positioned so that at least a portion of the peripheral annular region (124,126) is located above the at least one waveguide (114,116). The current isolation region (128) is configured to occupy at least a portion of a central region of the microdisk and has a relatively lower refractive index and relatively larger bandgap than the peripheral annular region.

摘要： In a method for the production of a single photon source with a given operational performance, the given operational performance for the individual photon source may be fixed by a directed setting of the fine structure gap of the excitonic energy level for at least one quantum dot. The at least one quantum dot is produced with a quantum dot size corresponding to the fine structure gap for setting.

摘要： A micro-cavity resonator (100) including a micro-cavity (110) capable of high and ultra-high Q values and a silicon substrate (120). Portions of the silicon substrate (120) located below a periphery of the micro-cavity (110) are removed to form a pillar, which supports the micro­cavity (110). Optical energy travels along an inner surface of the micro-cavity.

摘要： Laser comprising a first lasing microdisk (10), microcylinder or microannulus defining a microcavity having a circular cross-sectional periphery and a second waveguiding micromember (12) in a different plane and optically coupled by resonant photon tunnelling. The second waveguiding micromember includes a light output coupling (18) for providing light output from the laser without adversely affecting the Q value and low lasing threshold of the microcavity.
