Yes , I have read the article you have mentioned multiple times in the past. However the article doesn't provide a clear explanation of what a mode is or what distinguishes single mode from multi mode at the very basic level.
Thank you Andy.
Can you also explain the physical interpretations of various modes ? I know that modes are solutions to the helmholtz equations of a waveguide (obtained by combining maxwell's equations and boundary counditions).I'm looking for a non or less mathematical answer.
What actually is a mode of optical fiber propagation?Is it similar to modes which correspond to various configurations as in standing waves on a string ? Also How correct is it to consider no. of rays as no of modes?
Hey everyone.I'm Sujan from India.I'm a physics enthusiast and i find this forum very helpful . Looking forward to some productive and interesting physics discussions.
