By using this triplet scavenging host material which has a faster rate of triplet relaxation, the triplets formed on emitter material can be effectively scavenged out (Figure 1). We demonstrate that an ordinary cost-effective broadband Fabry–Pérot laser diode at the hundreds of milliwatts level, self-injection-locked to a microresonator, can be efficiently transformed to a powerful single-frequency, ultra-narrow-linewidth light source with further transformation to a coherent soliton comb oscillator. For analysis of the considered effect, original theoretical model taking into account self-injection locking effect, mode competition and Bogatov asymmetric mode interaction was developed and numerical modeling was performed. For optimal construction of such devices it is necessary to know the parameters of the locking mode, which is a challenging task. Therefore, when triplet accumulation takes place, the organic materials could not reach to its laser threshold, because the decreasing of radiative singlet population leads to hampering the photon density in the laser cavity. 1 cm³, and does not require on-chip filters and heaters, thus simplifying the integrated microcomb.
