Abstract:
Consistent with the present disclosure, a photonic integrated circuit (PIC) is provided that has 2 N channels (N being an integer). The PIC is optically coupled to N optical fibers, such that each of N polarization multiplexed optical signals are transmitted over a respective one of the N optical fibers. In another example, each of the N optical fibers supply a respective one of N polarization multiplexed optical signals to the PIC for coherent detection and processing. A multiplexer and demultiplexer may be omitted from the PIC, such that the optical signals are not combined on the PIC. As a result, the transmitted and received optical signals incur less loss and amplified spontaneous emission (ASE) noise. In addition, optical taps may be more readily employed on the PIC to measure outputs of the lasers, such as widely tunable lasers (WTLs), without crossing waveguides.

Claim (Index 1):
An optical device, comprising:\n a substrate; N lasers provided on the substrate; 2N modulators provided on the substrate, each of first N modulators of the 2N modulators respectively modulating a first portion of light generated by a respective one of the N lasers, each of second N modulators of the 2N modulators respectively modulating a second portion of light generated by a respective one the N lasers; first N waveguides, each of which being optically coupled to a respective one of the first N modulators, each of the first N waveguides extending to an edge of the substrate and supplying a corresponding one of first N modulated optical signals; and second N waveguides, each of which being optically coupled to a respective one of the second N modulators, each of the second N waveguides extending to an edge of the substrate and supplying a corresponding one of second N modulated optical signals, each of the first N modulated optical signals and each of the second N modulated optical signals including an in-phase component and a quadrature component, the first and second waveguides being provided on the substrate.
