摘要:
Consistent with the present disclosure, an arrayed waveguide grating (AWG) is provided that includes first inputs and second inputs. Each of the first inputs receives a corresponding one of a plurality of first optical signals, each of which has a corresponding one of a plurality of wavelengths. Second inputs are also provided, such that each second input is preferably provided between two adjacent first inputs. Each of the second inputs receives a corresponding one of a plurality of second optical signals, and each of the second plurality of optical signals has a corresponding one of those wavelengths. Each of the first plurality of optical signals, however, has a first polarization and each of the second plurality of optical signals has a second polarization different than the first polarization. Since the first optical signals are supplied through AWG inputs that are offset from the inputs that receives second optical signals, the first optical signals are supplied at a first AWG output that is spaced from a second AWG output that supplies the second optical signals. The second optical signals are supplied through the second output even though the second optical signals have the same (or substantially the same) wavelengths as the first optical signals. Accordingly, a single AWG may be provided to multiplex both first and second optical signals, thereby simplifying PIC design.
