We demonstrate highly circularly polarized emission from quantum dots in semiconductor chiral photonic crystals. The emission is influenced by the difference in density of states between the orthogonal circular polarizations at the polarization band edge.
We report experimental progresses in cavity quantum electrodynamics using H1 and H0-type photonic crystal nanoacvities embedding single quantum dots. Strong coupling and enhanced optical Stark effect in these systems with large g/κ will be discussed.
We discuss high density optical interconnects integrating an arrayed laser diode, silicon optical modulators, and germanium photodetectors on a single silicon substrate. A 5-Gbps error free data transmission with a 3.5-Tbps/cm2 transmission density was demonstrated. Moreover, recent advances in silicon-InAs/GaAs hybrid quantum dot lasers by using a direct wafer bonding technique is discussed. We achieved...
