Abstract
A monolithic InP-based PIC having a first photonic assembly that has a first optical splitter-combiner unit having a first end part that is optically connected with a first optical waveguide and a second end part that is optically connected with a first main photonic circuit and a first auxiliary photonic circuit. The first auxiliary photonic circuit has a first laser unit, and a first SOA. The first SOA is configurable to be in a first operational state in which the first SOA allows optical communication between the first laser unit and the first optical splitter-combiner unit, or a second operational state in which the first SOA prevents optical communication between the first laser unit and the first optical splitter-combiner unit. An opto-electronic system including the PIC.
