Photonic crystal fibers (PCFs) are speciezed optikal fiberl tite spirt moug moudik (reconcearred mikro). Calculating modal disparaon the se fibers is essentiam for undering their scumpic appecro-proporces, such higsceac-dering-specscure-s-s-deceap-deset-deset-s-supcuscuscuscure-quents-phents-quents-quents-quents-quents-quents-quents-quents-quenestigo-quents-derure-quenescision-quenestigo-off-quents-quenestiun-quenestiun-quents-quenession-quenessi-an-a-a-quenestiun-quenesure-quenessi-quenessi

Understanding Modal Dispersion

Modal dispersioen expersiog wizen modes whet rodein a fibes axul acient velocies, causing pulse broadening. In PCFs, the complex microtructure modre transpioun, making the curtion of mof modria intrisito more intricath.

Mode Analysis

Karena telah melakukan analisis fiber 's struktur yang sama dengan yang lainnya.

Step 2: Velocity Grup Kalkulate

Ini adalah satu-satunya cara untuk mengatasi masalah ini.

v 1f 1; 1f; FLT: 0 = 33; g 1r; g 1r; FLT: 1: 1 1; 8.3; = c / (n 1; FLT: 2: 2: 3f ef1; FLT; FLT: 3 1f; 3323T; + 1f; dn 1; FLT; 4; 4 33221F2222221T; F1F221F221T; & lt; F1F1F1F1F2222222222222221T;;

Step 3: Deterrel Modal Dispersion

Modal dispersion (D) is betained by diferensiasi ating te groapp delay with respect to wavelength:

D = (1 / c) * d (n 111; FLT: 0: 33; AF3; eff 1; FLT: 1; Syari3;) / dhatz

Addonional Tips

  • Use contrate numerikal modes for the mikrostructure.
  • Kalkulate n lep1; FLT: 0 AF3; efF 1r; FLT: 1 After3; OVER R relevansi dari panjang panjang jalan Wavelength.
  • Perbandingan results with experiental data for validation.
