Abstract Simulation of the immersed light source with microstructure on the emitting surface is critical for next generation optical and bio-photonics components. Several design procedures that corresponding to the modulation of the emitting pattern is addressed. The writers are at present operating on a MOST project “Investigation of Solid Human Eye Model with 3D Printing Technology and the Evaluation on the Associate Specialized Optoelectronic Sensing Structures Fabrication to the Biocompatible Surface”. We are preparing the methodology that can construct the human eye model with immersed emitting energy by the 3D printing material, and furnishes the real time estimation on the image qualities of the human eye. Our aim is to build a practical platform to evaluate the immersed optical-electronic components of the human eye. By doing this, the evaluation of the visual qualities can be amended, and it becomes possible for us to fill in an accurate measurement system that based on the eye model with immersed source. In this account, we provide several comments on the conduct of the immersed light source and the application to the details human eye modeling. Keywords Immersed, Human Eye, 3D Printing 1. Introduction Layer structure with light source immersed in the material provides as important applications for information display [1-8]. One of the applications for such device is to develop the optoelectronic component for the building and evaluation on the metrics of the (artificial) human eye. It is anticipated that a flexible and emitting light source layer can be attached or embedded in the human eye for specific uses. Granting to the comments by ophthalmologists, we realized that the current clinicians often meet the difficulties to describe the visual improvement of the patients, before and after the discussion or the operating room. No question those expensive facilities can simultaneously assess the visual metrics of the patients. Yet, for the patients and relevant, it is not easy to understand these complicated medical conditions and phenomena. On the other hand, the specialist sometimes will be difficult to predict and interpreted the possible effects of the treatment, for the unexpected scenario that the patients will endure-through for their daily life (such as Halo, glare phenomena while driving under different visual/head position). Moreover, for the upcoming aging society, to depict the subjective visual experience of the patient may not be easy - wearable and immersed type device is possible one of the answers. Based on these demands, this report will pay attention on the ray tracing of the immersed layer device. Referable to the complicated fabrication procedures for these novel devices, there are sometimes contradictions between the numerical simulation and the experiment report. For example, it is anticipated that the projected light source that immersed under the tissue, without textures on the top emitting surface should take in a flatten apodization for the smaller solid angle region, while the one with microstructure will lead to the Lambertain pattern (due to the increasing of the extraction efficiency). However, experimental results differ for single layer and multi-layers situations. This is imputable to the combinations between the refractive index, interface conditions and the surface properties for each layer that lead to these disagreements. Such divergence in the planning stage will cause serious and severe consequences for developing medical applications. To clarify such contradictions, we demonstrate the emitting patterns of a single layer immersed light source to prevent possible issues for practical application with 3D printing. 2.
