    摘要: Nitride optoelectronic devices that have asymmetric double-sided structures and methods fabricating such structures are disclosed. Two n-type III-N layers are formed simultaneously over opposite sides of a substrate with substantially the same composition. Thereafter, a p-type III-N active layer is formed over one of the n-type III-N layers but not over the other.

    摘要: Methods and systems permit fabricating structures using liquid sources without active temperature control. A substrate is disposed within a substrate processing chamber. A liquid source of a group-III precursor is provided in a bubbler. A push gas is applied to the liquid source to drive the group-III precursor into a vaporizer. A carrier gas is flowed into the vaporizer. A flow of vaporized group-III precursor carried by the carrier gas is injected from the vaporizer into the processing chamber. A nitrogen precursor is flowed into the processing chamber. A group-III nitride layer is deposited over the substrate with a thermal chemical vapor deposition within the processing chamber using the vaporized group-III precursor and the nitrogen precursor.

    摘要: Methods are provided of fabricating compound nitride semiconductor structures. A group-III precursor and a nitrogen precursor are flowed into a processing chamber to deposit a first layer over a surface of a first substrate with a thermal chemical-vapor-deposition process. A second layer is deposited over a surface of a second substrate with the thermal chemical-vapor-deposition process using the first group-III precursor and the first nitrogen precursor. The first and second substrates are different outer substrates of a plurality of stacked substrates disposed within the processing chamber as a stack so that the first and second layers are deposited on opposite sides of the stack. Deposition of the first layer and deposition of the second layer are performed simultaneously.

    摘要: An improved tunnel junction structure and a VCSEL that uses this structure is disclosed. The tunnel junction includes first, second, and third layers that include materials of the InP family of materials. The first layer is doped with n-type dopant species to a concentration of 1019 dopant atoms per cm3 or greater. The second layer is doped with Zn to a similar concentration and is in contact with the first layer. The interface between the first and second layers forms a tunnel junction. The third layer includes a material that retards the diffusion of Zn out of the second layer. The third layer preferably includes undoped AlInAs. The tunnel junction structure of the present invention can be utilized in a VCSEL having an active layer between first and second mirrors that are both constructed from n-type semiconductor layers.

    摘要: An optical modulator comprises a first waveguide layer and a barrier layer, and a quantum well layer sandwiched between the first waveguide layer and the barrier layer, where the quantum well layer has a graded composition that varies the bandgap energy of the quantum well layer between a minimum bandgap energy and the bandgap energy of at least one of the first waveguide layer and the barrier layer.

    摘要: A modulated light emitter having a laser and modulator constructed on a common substrate. The light emitter includes an active layer having a quantum well (QW) layer sandwiched between first and second barrier layers. The active layer includes a laser region and a modulator region connected by a waveguide. The laser region emits light when a potential is applied across the active layer in the laser region. The modulator region has a first state in which the modulator region absorbs the generated light and a second state in which the modulator region transmits the generated light. The modulator region assumes either the first or second state depending on the potential across the modulator region. The QW layer in the modulator region is under a tensile strain, which provides improved light absorption in the first state.
