Two-wavelength butt-joint diode lasers for the difference- and stum-frequency generation Conference Paper uri icon


  • Successful implementation and prospects of the new design of the nonlinear mixing heterolasers, the 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. In the implemented GaAs/lnGaAs/lnGaP Butt-Joint Laser, we obtain the sum-frequency and the second-harmonic signals at the same power level, which indicate the possibility of an efficient difference-frequency generation in these devices. We show that the spectral control of the coupled oscillators is possible by changing the Q-factors and pumping of diodes, which provides a wide tuning of the mid/far-IR output. The mid/far-IR measurements, the optimization of the Butt-Joint Laser, and the investigation of the spatial and spectral competition of lasing modes are underway.
