| Summary: | We investigate the effect of temperature on the supercontinuum generation of CS<sub>2</sub> single-hole liquid core optical fiber (LCOF). By solving the generalized nonlinear Schrödinger equation, the effect of the temperature on spectral broadening, coherence, soliton effects, and modulation instability was analyzed. The results turn out that the supercontinuum generation by pumping the LCOP with 1.95-μm laser is robust over a broad temperature range (15-45 °C). The optimal temperature to generate the broadest spectrum of SC via LCOF is 15 °C, which is independent on the pump power. The coherence of the generated SC is independent on the temperature at low pump power (such as P0 = 4 kW), while at a high pump power (such as P 0 = 40 kW) the coherence of the long wave (around 2600 nm) tends to be deteriorated at low temperature (e.g., 10 °C). The underlying reason for such phenomenon has been discussed as well.
