Summary form only given. The new design of the nonlinear mixing heterolasers, Butt-Joint Laser, where two butt-joined laser diodes are optically coupled but injection pumped separately, are presented. Two diode lasers operate at slightly different frequencies in the near-IR range and are mounted top side down on a mutual heat sink with their facets touched or separated by a few micron distance in such a way that their waveguides are aligned in the transverse direction. This robust design guarantees stable CW room-temperature two-wavelength generation and provides an efficient nonlinear optical mixing. The latter results in the difference-frequency (terahertz) as well as the sum-frequency and second-harmonic radiation in the standard edge-emitting geometry. The surface-emitting schemes of the Butt-Joint Lasers are also proposed.
