Analysis of field evolution and regulation inside a microcavity with thermal effect

The influence of thermal effects on the field within the microcavity has been investigated. Results show that these thermal effects can induce thermal detuning, which promotes the excitation of solitons under initial conditions of zero detuning. However, the occurrence of soliton generation during the thermal process is contingent upon the intensity of the pump power. Low pump power enhances soliton generation, whereas high pump power increases the probability of generating multiple pulses. In addition, thermal detuning is enhanced because of the accumulation of heat, which leads to the eventual elimination of the soliton or multi-pulse. To maintain transient soliton, the pump wavelength is linearly scanned to compensate for excessive thermal detuning after soliton generation. Thus, solitons can be held consistently. Moreover, the scanning speed of the pump wavelength and the regulated pump power influence the regulated field. Various special fields, including breather soliton, equidistant double pulses, or multi-pulse, are generated. The research results are essential for studying soliton generation and regulation in a microcavity with thermal effects.
