Two dimensionally arrayed semiconductor light sources are important for various applications. Recently surface emitting laser diodes (SE-LD) as well as light emitting diodes (SE-LED) are being developed. This paper proposes new structures of the laser diode (LD) and the light emitting diode (LED) with an extended active region along the direction of optical output, by means of the Coaxial Transverse Junction (CTJ) structure, whose p-n junction is cylindrical and perpendicular to the substrate.
