Abstract
A multi-lane optical apparatus is disclosed. The optical apparatus includes monitor photodiodes (mPD) whose number corresponds to a number of lanes. The mPDs are arranged in an array so as to intersect optical axes of the respective lanes. The mPD has a light-sensitive area and an electrode that are arranged on a diagonal connecting two corners. The light-sensitive area is disposed offset from the center of the mPD. The mPDs in outermost are disposed such that the respective electrodes face inward.
