Abstract:
Methods and systems for a photonically enabled complementary metal-oxide semiconductor (CMOS) chip are disclosed. The CMOS chip may comprise a plurality of lasers, a microlens, a turning mirror, and an optical bench, and may generate optical signals utilizing the lasers, focus the optical signals utilizing the microlens, and reflect the optical signals at an angle defined by the turning mirror. The reflected optical signals may be transmitted into the photonically enabled CMOS chip, which may comprise a non-reciprocal polarization rotator, comprising a latching faraday rotator. The CMOS chip may comprise a reciprocal polarization rotator, which may comprise a half-wave plate comprising birefringent materials operably coupled to the optical bench. The turning mirror may be integrated in the optical bench and may reflect the optical signals to transmit through a lid operably coupled to the optical bench.
