High-performance and low-cost sensors are critical devices for high-throughput analyses of bio-samples in medical diagnoses and life sciences. This report demonstrates GaInAsP photonic crystal nanolaser sensor, which detects the adsorption of bio-molecules from the lasing wavelength shift. It is a promising device, which balances a high sensitivity, high resolution, small size, easy integration, simple...
Semiconductor photonic nanostructures, i.e. photonic crystals (PCs) and high index contrast structures (HICs), have become worldwide topics in this decade. They strongly control light emission and propagation, and so allows novel phenomena and device applications. PCs are artificial muIt i-dimensional periodic structures whose period is of the order optical wavelength. Through active studies in these...
This presentation shows the recent progress on photonic molecules (PMs) based on semiconductor micro/nanolasers. Microdisk cavities easily achieve the room temperature cw lasing by a whispering gallery mode. The splitting of bonding and antibonding modes and the miniband formation by the mode coupling are clearly observed in microdisk PMs. By using the nonuniform pumping, the bistable mode switching...
