Abstract: Structures for integrated lasers, systems including integrated lasers, and associated fabrication methods. A ring waveguide and a seed region are arranged interior of the ring waveguide. A laser strip extends across a portion of the ring waveguide. The laser strip has an end contacting the seed region and another opposing end. The laser strip includes a laser medium and a p-n junction capable of generating electromagnetic radiation. The p-n junction of the laser strip is aligned with a portion of the ring waveguide.

Abstract: Structures for an optical switch, structures for an optical router, and methods of fabricating a structure for an optical switch. A phase change layer is arranged proximate to a waveguide core, and a heater is formed proximate to the phase change layer. The phase change layer is composed of a phase change material having a first state with a first refractive index at a first temperature and a second state with a second refractive index at a second temperature. The heater is configured to selectively transfer heat to the phase change layer for transitioning between the first state and the second state.

Abstract: A method of forming a CMOS device and a GaN PA structure on a 100 Si substrate having a surface orientated in 111 direction and the resulting device are provided. Embodiments include forming a device with a protective layer over a portion of a Si substrate; forming a V-shaped groove in the Si substrate; forming a buffer layer, a GaN layer, an AlGaN layer and a passivation layer sequentially over the Si substrate; forming trenches through the passivation and the AlGaN layers; forming second trenches through the passivation layer; forming electrode structures over portions of the passivation layer and filling the first and second trenches; removing portions of the passivation layer, the AlGaN layer and the GaN layer outside of the V-shaped groove down to the buffer layer; forming a dielectric layer over the Si substrate; and forming vias through the dielectric layer down to electrode structures and the device.

Abstract: Fabrication methods and device structures for a silicon controlled rectifier. A cathode is arranged over a top surface of a substrate and a well is arranged beneath the top surface of the substrate. The cathode is composed of a semiconductor material having a first conductivity type, and the well also has the first conductivity type. A semiconductor layer, which has a second conductivity type opposite to the first conductivity type, includes a section over the top surface of the substrate. The section of the semiconductor layer is arranged to form an anode that adjoins the well along a junction.

Abstract: Fabrication methods and device structures for heterojunction bipolar transistors. A first emitter of a first heterojunction bipolar transistor and a second collector of a second heterojunction bipolar transistor are formed in a device layer of a silicon-on-insulator substrate. A first base layer of a first heterojunction bipolar transistor is epitaxially grown on the device layer with an intrinsic base portion arranged on the first emitter. A first collector of the first heterojunction bipolar transistor is epitaxially grown on the intrinsic base portion of the first base layer. A second base layer of the second heterojunction bipolar transistor is epitaxially grown on the device layer with an intrinsic base portion arranged on the second collector. A second emitter of the second heterojunction bipolar transistor is epitaxially grown on the intrinsic base portion of the second base layer. A connection is formed between the first emitter and the second collector.

Abstract: Device structures and fabrication methods for a heterojunction bipolar transistor. A collector of the device structure has a top surface and a sidewall that is inclined relative to the top surface. The device structure further includes an emitter, an intrinsic base that has a first thickness, and an extrinsic base coupled with the intrinsic base. The extrinsic base has a lateral arrangement relative to the intrinsic base and relative to the emitter. The intrinsic base has a vertical arrangement between the emitter and the top surface of the collector. The sidewall of the collector extends laterally to undercut the extrinsic base. The extrinsic base has a second thickness that is greater than a first thickness of the intrinsic base.
