Modes in a fibre

  1. May 13, 2015 #1
    So I've got the equation for 'allowed angles of propagation':
    SinΘp = pλ / 2πdnf
    With p is the mode, λ the wavelength, d the width and n the refractive index.

    I'm just not sure what to do with this equation, and my lecture notes don't go into any more detail.
    For example, if I knew the the max number of modes (p) and I put this into the equation, would the value I get for the angle be the maximum value for propagation in this fibre?
    I know this is probably something simple I should be able to figure out, but my mind is all over the place atm and I seem to be struggling to think things through and make simple connections :P
