Difference between Optical bandpass filter and normal/electr

Hi there, Im very new to optical domain, and im only used to the common bandpass filter that we use on circuits, those RLC and OP-AMP based bandpass filter.

I went through few books and cant really find the difference, do anyone have any link regarding this issue or idea about this.

Thank you.

Usual optical thin layer filters have little in common with lumped element electrical devices, they are more like transmission line or digital filters.

The most important difference is a practical one: You won't be able to build optical filters in a DIY manner, unless you have special, rather expensive and bulky equipment.

[b]Im still in the stage of simulating the filter, the problem here is, i need the transfer function of a optical bandpass filter in order to simulate the entire channel of optical network.

But then, normal circuity filters transfer function could be derived by considering capacitors and resistors and inductors. But in optical case, how do we get them. I went through a few papers, but yet i cant get the idea.
