Abstract
An optical module includes a fiber array, a laser diode array, a photodiode array and a micro-lens array. The fiber array includes optical fibers which are divided to a transmitter group and a receiver group. The laser diode array includes laser diodes which are grouped in a transmitter group. The photodiode array includes photodiodes which are divided to a monitor group and a receiver group. The laser diode array is provided between the fiber array and the photodiode array. The optical fibers of the transmitter group are optically aligned with the laser diodes of the transmitter group, respectively. The micro-lens array is provided between the laser diode array and the photodiode array, and optically aligns the laser diodes of the transmitter group and the optical fibers of the receiver group with the photodiodes of the monitor group and the photodiodes of the receiver group, respectively.
