FDTD method analysis tool for LEDs with two different surface structures.
Two types of LED device structures with different surface shapes were simulated using the FDTD method in APSYS, resulting in an angle-dependent light intensity distribution. The differences in surface shape are reflected in the light intensity. A 3D structure can be simulated using the same method as in 2D.
Device modeling and analysis tools for photonic crystal LEDs
This introduces the points of modeling and analysis examples of photonic crystal LEDs (PhCLED). It considers simulations based on photonic crystal LEDs with DBR. (2D/3D drift-diffusion model. Band analysis through physical simulation. Spontaneous emission and guided mode. Consideration of the depth of air holes, etc.) Additionally, it presents an analysis of guided multimodes using InGaN photonic crystal LEDs. The results of these simulations are consistent with reported theories and experiments.
Device modeling and analysis of cross-light using RCLED devices as an example.
Introducing various types of analyses of RCLEDs. (Comparing experimental results using InGaAs/AlGaAs RCLED as an example. RCLED with a structure similar to VCSEL using GaAs/AlGaAs materials with multiple quantum wells (MQW). RCLED with detuned DBR. RCLED with a long resonator.) The device simulator APSYS enables an all-in-one analysis and design approach.
