Photoic crystal nanobeam cavity devices for on-chip integrated silicon photonics

Abstract

Integrated circuit (IC) industry has fully considered the fact that the Moore’s Law is slowing down or ending. Alternative solutions are highly and urgently desired to break the physical size limits in the More-than-Moore era. Integrated silicon photonics technology exhibits distinguished potential to achieve faster operation speed, less power dissipation, and lower cost in IC industry, because their COMS compatibility, fast response, and high monolithic integration capability. Particularly, compared with other on-chip resonators (e.g. microrings, 2D photonic crystal cavities) silicon-on-insulator (SOI)-based photonic crystal nanobeam cavity (PCNC) has emerged as a promising platform for on-chip integration, due to their attractive properties of ultra-high Q/V, ultra-compact footprints and convenient integration with silicon bus-waveguides. In this paper, we present a comprehensive review on recent progress of on-chip PCNC devices for lasing, modulation, switching/filting and label-free sensing, etc.

Surface Plasmonic Sensors: Sensing Mechanism and Recent Applications

“…As for the future development of plasmonic sensors, we envision that there is still plenty of room to explore in the category of classical optics. Besides the platforms of planar metastructures and optical fibers, the whispering-gallery mode (WGM) microcavities and photonic crystals (PCs) have received much attention for their ultrahigh-Q factors and moderate mode volumes [ 43 , 270 , 271 , 272 , 273 , 274 ]. Integrating the plasmonic structures in WGM and PCs, the ultrahigh sensitivity for single-molecule and single-ion detection have been achieved [ 274 , 275 , 276 ].…”

In respect of the plasmonic materials, the most used noble metals such as silver and gold have some limitations for plasmonic devices considering their inherent optical loss, high cost (for gold) and oxidation issue (for silver).…”

Simultaneous Detection of Relative Humidity and Temperature Based on Silicon On-Chip Cascaded Photonic Crystal Nanobeam Cavities

“…Simultaneously, Ian M. White demonstrated a novel sensor architecture based on a liquid-core optical ring-resonator (LCORR) in which a fused silica capillary was utilized to carry the aqueous sample and to act as the ring resonator [19]. However, compared with on-chip resonators (e.g., microring resonator [2], 2D-PhC cavities [10]), SOI-based photonic crystal nanobeam cavities (PCNCs) are very promising in on-chip integration owing to their attractive characteristics of ultrahigh Q/V, ultra-compact size, flexible structure design, and ease of integration [20,21]. Furthermore, PCNCs are suitable for dual-parameter sensing because these structures can be designed cleverly to support various resonant modes, such as waveguide side-coupled double-cavity [15] and single multimode cavity [22,23].…”
