1 × N active multi-mode interferometer laser diode (MMI LD) is proposed and demonstrated to realize single-wavelength edgeemitter without using grating configuration. As the 1 × N active-MMI LDs are based on longitudinal mode interference, they have a potential of singlewavelength emission without incorporating any grating layer on/beneath active layer. The fabricated devices showed single-wavelength emission with a side mode suppression ratio (SMSR) of 12 dB at a wavelength of 1.57 ?m.
