Two Chip-Scale Photonic Systems For Optical Data Transmission & Microwave Photonics
By Technical Paper Link - 21 May, 2022 - Comments: 0

New research paper "Microcomb-driven silicon photonic systems" from Peking University, UCSB, and Peng Cheng Laboratory. Abstract "Microcombs have sparked a surge of applications over the past decade, ranging from optical communications to metrology. Despite their diverse deployment, most microcomb-based systems rely on a large amount of bulky elements and equipment to fulfil their desir... » read more

Motional narrowing, ballistic transport, and trapping of room-temperature exciton polaritons in an atomically-thin semiconductor
By Technical Paper Link - 10 Dec, 2021 - Comments: 0

Abstract "Monolayer transition metal dichalcogenide crystals (TMDCs) hold great promise for semiconductor optoelectronics because their bound electron-hole pairs (excitons) are stable at room temperature and interact strongly with light. When TMDCs are embedded in an optical microcavity, excitons can hybridise with cavity photons to form exciton polaritons, which inherit useful properties from... » read more

Quantum well interband semiconductor lasers highly tolerant to dislocations
By Technical Paper Link - 11 Nov, 2021 - Comments: 0

Abstract "III-V semiconductor lasers integrated on Si-based photonic platforms are eagerly awaited by the industry for mass-scale applications, from interconnect to on-chip sensing. The current understanding is that only quantum dot lasers can reasonably operate at the high dislocation densities generated by the III-V-on-Si heteroepitaxy, which induces high non-radiative carrier recombination ... » read more

Sputtered transparent electrodes for optoelectronic devices: Induced damage and mitigation strategies
By Technical Paper Link - 03 Nov, 2021 - Comments: 0

Abstract: Summary "Transparent electrodes and metal contacts deposited by magnetron sputtering find applications in numerous state-of-the-art optoelectronic devices, such as solar cells and light-emitting diodes. However, the deposition of such thin films may damage underlying sensitive device layers due to plasma emission and particle impact. Inserting a buffer layer to shield against such da... » read more

Graphene and two-dimensional materials for silicon technology
By Technical Paper Link - 02 Oct, 2020 - Comments: 1

Abstract: "The development of silicon semiconductor technology has produced breakthroughs in electronics—from the microprocessor in the late 1960s to early 1970s, to automation, computers and smartphones—by downscaling the physical size of devices and wires to the nanometre regime. Now, graphene and related two-dimensional (2D) materials offer prospects of unprecedented advances in device ... » read more
