Dear Sir/Madam,
Happy New Year!
I am trying to simulated the fiber with NA 0.22. For this I have taken Core RI 1.49 and claculated the cladding RI for desired NA, it is coming 1.473. I have used the formula NA = sqrt(core_RI^2 - cladding_RI^2).
I am using “cylindrical volume” to simulate the fiber in non-sequential mode. Is this the right approach to have a fiber with desired NA in Zemax? Doubting because…...
When I changed the NA of fiber to 0.5(core RI 1.45 - cladding RI 1.3610), just to check wheater coupling efficiency is changing or not. I am getting same power at detector, placed at front surface of fiber! and hence same Coupling efficiency.
I am attaching the zemax file of my Simulation for your reference.
A comment would be appreciated.
Thankyou.
