Abstract:
An optical device may include a slab, a first waveguide extending from a first portion of the slab to supply multiple first optical signals to the first portion of the slab, multiple second waveguides coupled to a second portion and to a third portion of the slab. The optical device may include multiple third waveguides provided extending from a fourth portion of the slab to direct a corresponding one of the multiple first optical signals away from the slab, a fourth waveguide extending from the fourth portion of the slab to supply multiple second optical signals to the fourth portion of the slab, and multiple fifth waveguides extending from the first portion of the slab to direct a corresponding one of the multiple second optical signals away from the slab. The optical device may include circuits to receive the first optical signals, the second optical signals, and local oscillator signals.
