22. Epitaxy of GaAs-based long-wavelength vertical cavity lasers
Abstract : Vertical cavity lasers (VCLs) are of great interest aslow-cost, high-performance light sources for fiber-opticcommunication systems. They have a number of advantages overconventional edge-emitting lasers, including low powerconsumption, efficient fiber coupling and wafer scalemanufacturing/testing. READ MORE

23. Strong light-matter coupling: from traditional to cavity-free polaritons
Abstract : Polaritons are formed when light and matter interact strongly. For this to occur, photons and transitions in a material must exchange energy faster than the dissipation rate of the interacting components. Polaritons have shown the ability to change such material properties as photophysics, chemical reaction rates, transport, etc. READ MORE

24. CFD MODELLING AND EXPERIMENTS ON AERATOR FLOW IN CHUTE SPILLWAYS
Abstract : A chute spillway is a typical component of large dams for discharging floods. Because of the high water head, the flow velocity in the chute is often in excess of 20 m/s. Consequently, the structure is usually prone to cavitation damages. Flow aeration is evidenced to efficiently eliminate or to mitigate the damages. READ MORE

25. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers
Abstract : In this work, a comprehensive dynamic model has been developed for simulating a novel semiconductor laser type, referred to as the Vertical-Cavity Surface-Emitting Laser (VCSEL). The high-speed behavior was simulated and compared to experiments, where excellent agreement was found. READ MORE
