Dura­tion and Inten­ded Audience

  • 3 hours per day | 4 days in sum
  • Opti­cal desi­gners and engi­neers in the field of dif­frac­tive gra­ting applications

Tech­ni­cal Environment

  • Par­ti­ci­pants will recei­ver fur­ther infor­ma­tion once the request has been successful.

Con­tent

Gra­tings are the most widely applied dif­frac­tive optics ele­ments in various opti­cal sys­tems. Vir­tual­Lab Fusion soft­ware pro­vi­des the Fou­rier modal method (FMM a.k.a. RCWA) and the thin ele­ment appro­xi­ma­tion (TEA) for gra­ting simu­la­ti­ons. This inter­ac­tive online trai­ning shows how to use the cor­re­spon­ding tech­no­lo­gies from Vir­tual­Lab Fusion to solve prac­ti­cal gra­ting mode­ling and design tasks for modern optics applications.

Lear­ning outcomes

  • ƒLearn how to con­s­truct the gra­ting geo­me­try and mate­ri­als; under­stand the basic theory of the mode­ling tech­no­lo­gies and their dif­fe­ren­ces; use the soft­ware tools for gra­ting ana­ly­sis and design.
  • Prac­tice hands-on with sel­ec­ted rigo­rous mode­ling examp­les, inclu­ding bla­zed gra­ting, rec­tan­gu­lar gra­ting, slan­ted gra­ting, holo­gra­phic volume gra­ting, and metagrating.
  • Design work­flow dis­cus­sed along examp­les, like moth-eye anti-reflec­tion gra­ting, wave­guide cou­pling gra­ting, pola­riza­tion-insen­si­tive pulse com­pres­sor gra­ting, and beam-split­ting metagrating.
