Photo excitations of ethene give 4 membered rings.

Think about FMO theory.

This gives a 4 membered rings. If one of the alkenes was a 5 membered cycle (e.g. cyclopentene), you would get a 5 and a 4 ring fused together.



If you want to form the 5 members cycle, you can use a 1,3-dipolar cycloaddition, [3+2]:
