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.

What is the difference between the photon interaction mechanisms in emission due to absorption and reflection?

Thanks Andy. Can you also provide a less mathematical but more intuitive explanation?

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?

Can Stimulated Emission in lasers be explained semi classically? If so, how?

How to add questions into the forum?

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.
