13. 9) the stimulated as well as spontaneous emission enhancement at the cavity resonance is proportional to the cavity mode separation, when the cavity resonance width is broader than the radiative lifetime broadening. In BP1T microdisks, the condition holds because the cavity resonance width is ∼5{6meV and the radiative lifetime is ∼1-10ns.
