Hybrid Cavity

We propose and demonstrate a hybrid cavity system in which an optical nanoantenna (NA) is evanescently coupled to a dielectric photonic crystal (PC) cavity. While the plasmonic component leads to strongly localized fields, photon storage mechanism is provided by the surrounding photonic crystal structure. The combined effect of plasmonic field enhancement and high quality factor opens new routes for the control of light-matter interaction at the nanoscale.

Light Matter Interaction

Two-dimensional perovskite materials have received wide interests due to their highly impressive optoelectronic properties. The combination of single crystalline perovskite as thin as several unit cells with graphene has not been demonstrated, which may have some outstanding performance for its high crystallinity and less defects. Here, high-quality 2D perovskite crystals as thin as several unit cells are synthesized and a broadband photodetector with a high on/off ratio of 4.28×103 is demonstrated. Based on this, we further fabricated a novel hybrid photodetector by growing single crystalline 2D CH3NH3PbI3 perovskite directly onto the graphene channel, and the resulting device shows an impressive photoresponsivity of 61.2 A/W that is six orders of magnitude over pristine perovskite photodetector. Also, a much faster response time of 130 ms is observed, which takes only one-tenth the response time of pristine perovskite photodetector. These results show that 2D graphene-perovskite heterostructure can be a promising candidate for highly efficient and low-cost optoelectronic applications.

The Ideal

In this chapter we study with the tools developed in Chapter 3 the basic models that are the foundations of light–matter interaction. We start with Rabi dynamics, then consider the optical Bloch equations that add phenomenologically the lifetime of the populations. As decay and pumping are often important, we cover the Lindblad form, a correct, simple and powerful way to describe various dissipation mechanisms. Then we go to a full quantum picture, quantizing also the optical field. We first investigate the simpler coupling of bosons and then culminate with the Jaynes–Cummings model and its solution to the quantum interaction of a two-level system with a cavity mode. Finally, we investigate a broader family of models where the material excitation operators differ from the ideal limits of a Bose and a Fermi field.

Two-dimensional (2D) materials driven by their unique electronic and optoelectronic properties have opened up possibilities for their various applications. The large and high-quality single crystals are essential to fabricate high-performance 2D devices for practical applications. Herein, IV-V 2D GeP single crystals with high-quality and large size of 20 × 15 × 5 mm3 were successfully grown by the Bi flux growth method. The crystalline quality of GeP was confirmed by high-resolution X-ray diffraction (HRXRD), Laue diffraction, electron probe microanalysis (EPMA) and Raman spectroscopy. Additionally, intrinsic anisotropic optical properties were investigated by angle-resolved polarized Raman spectroscopy (ARPRS) and transmission spectra in detail. Furthermore, we fabricated high-performance photodetectors based on GeP, presenting a relatively large photocurrent over 3 mA. More generally, our results will significantly contribute the GeP crystal to the wide optoelectronic applications.
