We introduce a new general class of hybrid optical filters, which reduce to either transversal or lattice filters in particular limits, and are suitable for implementation as planar lightwave circuits. They can be used to synthesize arbitrary periodic transfer functions with finite impulse responses. Design tradeoffs can be used to minimize insertion loss and optimize layout. Examples of filter synthesis are presented.
