The directed emission output of microdisk lasers through a coupled optical waveguide fabricated from the same heterostructure has been investigated. Disks with diameters of 30 and 40 µm containing an active region based on InGaAs/GaAs quantum dots were studied. To reduce absorption losses in the waveguide, a forward bias was applied to it. At a waveguide current of about 60 mA, a sharp (almost an order of magnitude) increase in the extracted optical power of the microlaser was observed, which the authors attribute to the achievement of the waveguide transparency state.
