Document Type and Number:
WIPO Patent Application WO/2019/131804
Kind Code:
A1
Abstract:
An optical module that provides a semiconductor modulator, an input lens system and first and second output lens systems, and two monitor photodiodes is disclosed. The semiconductor modulator provides an input port, first and second output ports, and two monitor ports in one side thereof. The input port and the first and second output ports face the input lens system and the first and second lens systems, respectively. The two monitor ports face the two monitor photodiodes, respectively. The first and second output ports are symmetrically disposed with respect to the input port in the one side. The two monitor ports are disposed in respective outer sides of the first and second output ports and symmetrically with respect to the input port.
