About Me

My name is Arti Agrawal and I am a scientist. I am currently employed as Senior Lecturer at City, University of London in the School of Engineering and Mathematical Sciences.

My research expertise is in Photonics, especially numerical modelling and simulation of photonic structures such as optical fibers, photonic crystals, solar cells, LEDs. I also have extensive experience in developing modelling methods based on techniques such as the Finite Element, Finite Difference methods.

I love bringing together approaches from different disciplines to solve problems in Photonics: for example bio-mimicry or inspiration from nature.

  1. Hi Arti…
    I came upon your blog during the search for the articles on simulations in photonics..
    It was interesting to read through your blog. I feel i am seeing myself on the other side with some fine tunings…
    introducing myself ,Sumathi,presently in Dubai as Lecturer…
    lets keep in touch further…

  2. Hiii Madam,

    I need your suggestion regarding experimental and theoretical research. If I got a PhD in both fields which is better to take? why ?

    • Hi Mahesh,

      a lot depends on the area/field you are interested in. so for different areas the answer might be different. some things to consider in making this decision:
      – how young/old the area is, what is the trend in it?
      – what is a valuable skill needed in this area: experimental, theoretical or both?
      – what is your own aim? to stay in this area evetually?
      – what do you enjoy?

      I hope this helps.

  3. hi my name is Basel , and i am a master degree student doing research about photonic crystal fiber as very high nonlinear and very low confinement loss . I have read your paper ,and then modeled the same structure with the same parameters as yours , to study the confinement loss of this structure . i get the minimum effective area ~=0.7[um^2] as yours , but very large confinement loss .
    NOW i am trying to modify the structure to minimize the confinement loss , so i will be grateful for your advice.
    please contact me on :


      • Respected Mam
        I have seen your research contributions.Its really great.Mam I have seen your book too.Mam I want to submit the research paper in Journal of European society Rapid publication but i am unable to find the link.mam can i send it directly via mail?If yes please let me know the mail id.Mam I am Dr.Himanshu Monga from Shimla,Himachal Pradesh,INDIA.
        Please help me in this regard.

        Warm Regards

  4. Hi
    I am Samiul and doing research on photonic crystal fiber. I read your papers on spiral pcf and got interested on that structure as it has some unique properties than conventional pcf. I came to know from your blog that you are doing your recent work on Archimedean spiral. What are the advantages of using this structure than equiangular spiral? Recently, i designed a equiangular pcf that shows high birefringence and high nonlinearity in the entire telecom band, I wilI be grateful to you, if you send me your designed fiber on Archimedean spiral.

  5. Respected Madam,
    I am working in the field of photonic crystal fibers and waveguides. I want to know about the optimization of perfectly matched layer (PML). What is the criteria of optimization of PML. Kindly, resolve my problem….

    • Thank you for writing in.

      To optimize PML there are a few things you can do:
      start by defining PML thickness to be about 10% of total window. Then vary this thickness to see the impact on results and where the reflections converge to a low value- choose that thickness. Other things to optimize by a little trial and error is the distance of PML from the waveguide/structure of interest- this can be different for different problems; the reflection coefficient and PML variables; the number of computation points used within the PML layer (these should not be too few or have too much spacing in bettwen them, while obviously you cant devote a lot of your mesh to PML, so its a tradeoff).

      I hope this helps.
      Kind regards

  6. Interestingly I came looking for an explanation of what numerical dispersion is to explain the impact of this in a groundwater resource model using two different methods of identifying where water is coming from in an aquifer. Your explanation was very clear and useful! Thanks
