Abstract:
Perfect absorbers are important optical components required by a variety of applications. While there is great interest in achieving highly absorptive materials exhibiting large broadband absorption using optically thick, micro-structured materials, it is still challenging to realize ultra-compact subwavelength absorber for on-chip optical/thermal energy applications. In this presentation, we will discuss nanocavity enhanced light-matter interaction in ultra-thin films and patterned hyperbolic meta-film with engineered and freely tunable absorption band. These on-chip absorbers can easily be integrated with other on-chip electronic/optoelectronic devices, which is promising to create new regimes of optical/thermal physics and applications.
