Very effective lecture sir. Please do continue

Thanks, I appreciate your step-by-step derivation. I wish you would provide a link in the description to the complete course. I cannot find where lecture 17 is for this series.

Sir.. Will u plzz..provide some more topics of optical engineering..that will be really helpful

am just curious... Are these scalar differential equations? ie are the complex amplitudes E1 and E2 also vectors? Also, is it implied that there are complex conjugates to be included in the differential equations? Thanks for the great lecture. Will it be possible to take formally in the near future?Alex

Nice

Around 18:05 , I don't get how the limit of sinc^2(dkz/2) becomes z^2, neither the equation, nor the verbal explanation.

how (dw/n1)the square comes in the expression for p2??? actually it is (dw/n2) square na????beacause no where in the derivation n1 comes!!!!
