Stable unidirectional emission hybrid deformed-ring microlaser coupled to a silicon waveguide

Mode characteristics are investigated to realize stable unidirectional emission for a locally deformed-ring resonator. Using DVS-BCB bonding technique, hybrid silicon deformed-ring microlasers are fabricated coupled to a silicon waveguide, and threshold current of 7 mA and unidirectional power output from CCW direction are obtained.
