In whispering gallery mode (WGM), the energy threshold for amplified spontaneous emission (ASE threshold) tends to be higher than the ASE threshold for general slab waveguides. To investigate the origin of this, we formulated the ASE threshold and compared the results of calculations with those of measurements.
