Abstract :
We devised a new output configuration for the Si-SOA hybrid laser which is suitable for high-power operation in terms of slope efficiency and suppression of nonlinear effects in a ring resonator. These advantages were theoretically evaluated. A proof-of-concept experiment demonstrated output power of > 7 mW and tunable operation with a range of 4.8 THz.
