<P>PROBLEM TO BE SOLVED: To provide a lasing device which can be driven with high modulation speed and has small effective parasitic capacitance, in particular, a lasing device which can be easily manufactured with low cost. <P>SOLUTION: The present invention provides a lasing device for use in an optical interconnection. The lasing device comprises: a first reflector and a second reflector; a confinement layer adapted to confine current within a current-confining aperture; and an active layer between the first and second reflectors. The active layer comprises a main active region aligned with the current-confining aperture and an auxiliary active region surrounding the main active region. The second reflector includes a first reflector region arranged on the current-confining aperture and a second reflector region surrounding the first reflector region. The second reflector region and the first reflector are configured to induce stimulated recombination in the auxiliary active region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
