Title:
Thermodynamic Upper Bound on Broadband Light Coupling with Photonic Structures
Authors:
Yu, Zongfu; Raman, Aaswath; Fan, Shanhui
Abstract:
The coupling between free space radiation and optical media critically influences the performance of optical devices. We show that, for any given photonic structure, the sum of the external coupling rates for all its optical modes are subject to an upper bound dictated by the second law of thermodynamics. Such bound limits how efficient light can be coupled to any photonic structure. As one example of application, we use this upper bound to derive the limit of light absorption in broadband solar absorbers. © 2012 American Physical Society.
