Abstract
Fourier modal method based quantitative analysis method of optical power flow and energy loss in general multi-block photonic structures with an internal dipole emitter is described. The analytic expressions of modal power flow and loss are derived for accurate and efficient quantitative analysis. It is revealed that a few dominating excited photonic modes substantially govern the internal energy flow and energy loss. The optical characteristics of the dominant modes are investigated.
Highlights
The quantitative analysis of optical power flow and energy loss is a fundamental analysis issue for many optical devices [1,2,3,4,5,6,7,8,9]
The in-depth analysis of external optical power extraction efficiencies and internal losses is crucial to the development of self-radiative optical devices such as light emitting diodes (LEDs) and organic light emitting diodes (OLEDs) [1,2,3,4,5] and optical energy devices such as solar cells [6,7,8,9]
Analyzing the photonic modes causing optical loss dominantly allows addressing its origin at the design stage and enhancing the device design strategy in terms of optical efficiency
Summary
The quantitative analysis of optical power flow and energy loss is a fundamental analysis issue for many optical devices [1,2,3,4,5,6,7,8,9]. The in-depth analysis of external optical power extraction efficiencies and internal losses is crucial to the development of self-radiative optical devices such as light emitting diodes (LEDs) and organic light emitting diodes (OLEDs) [1,2,3,4,5] and optical energy devices such as solar cells [6,7,8,9]. A Fourier modal method (FMM) [12] based quantitative modal analysis method of optical power flow and energy loss in photonic multi-block structures with internal dipole emitters is proposed.
