Photonic Crystal Fibres and COMSOL

Click For Summary

Discussion Overview

The discussion revolves around the use of COMSOL 3.5 for designing Photonic Crystal Fibres (PCFs) and tapered optical fibres. Participants are seeking guidance on the background layout for these designs, instructions for creating PCF structures in COMSOL, and resources for learning about COMSOL applications in photonics.

Discussion Character

  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant, Chris, inquires about the background layout in COMSOL, specifically whether the surrounding area should be defined as air or another object.
  • Chris requests instructions for creating a PCF structure in COMSOL and seeks recommendations for notes or books on COMSOL for photonic applications.
  • Another participant shares a link to a paper on confinement loss computations in PCFs, suggesting it may be helpful.
  • Chris responds that the paper is more theoretical and not particularly helpful for his needs, expressing a desire for a COMSOL file to begin his work.
  • A different participant suggests that Chris ask his question in the COMSOL Community for a potentially quicker response.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best resources or methods for using COMSOL for PCF design, and multiple views on the usefulness of the shared paper exist.

Contextual Notes

Chris's request for specific COMSOL files and practical guidance indicates a need for more applied resources, while the shared paper focuses on theoretical analysis, highlighting a potential gap in available materials.

Hello everyone, I am trying to understand COMSOL 3.5 and I am interested in Photonic crystal fibres and tapered optical fibres. First of all, could you please tell me what is the background of the layout? When you create a design/object, the rest area is air or I need to define another object as the environment?
Now, could you please tell me where I can find instructions of how creating a PCF structure in COMSOL? Furthermore, do you know any good notes/books for COMSOL for photonic applications??
Thank you in advance

Chris

Have you seen this paper yet on Confinement Loss Computations in Photonic Crystal Fibres using a Novel Perfectly Matched Layer Design? http://www.comsol.com/papers/1083/
It may help.

Yes my friend, I have already found this paper but its not really helpful because its more theoretical analysis. I need the COMSOL file, in order to start working in that. Do you have any other ideas?

Best Regards,
Chris
