  1. We have demonstrated, for the first time to our knowledge, self-injection locking of a distributed feedback diode laser to a multimode 4H-silicon carbide (4H-SiC) microring resonator, which is also used for the observation of resonant opto-mechanical oscillation in the cavity modes. While the fundamental transverse-electric mode family of the silicon carbide microring was optically pumped, Stokes light was generated in the adjacent fundamental transverse-magnetic resonant mode. The threshold of the process did not exceed 5 mW of light entering the cavity characterized by a loaded optical quality factor of 2 × 106. These results mark a significant milestone in unlocking the potential of 4H-SiC through turnkey soliton microcomb generation and empowering future advancements in areas such as cavity optomechanics using this versatile and quantum-friendly material platform.
