Where did you get the 55nH based notch from? I don't remember anything like that from the other LSC PD schematics. This is certainly a bad idea. You should remove it and put the notch back over by the other notch.

 Why is it a bad idea?

You mean putting both the 2-omega and the 55MHz notches next to each other right after the photodiode?
