Abstract
Methods and systems for a light source assembly for coupling to a photonically enabled complementary metal-oxide semiconductor (CMOS) chip are disclosed. The light source assembly may comprise a laser, a microlens, a turning mirror, and an optical bench, and may generate an optical signal utilizing the laser, focus the optical signal utilizing the microlens, and reflect the optical signal at an angle defined by the turning mirror. The reflected optical signal may be transmitted out of the assembly to grating couplers in the photonically enabled CMOS chip. The assembly may comprise a non-reciprocal polarization rotator, comprising a latching faraday rotator. The assembly 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 signal to transmit through a lid operably coupled to the optical bench.
