In this work we propose a temperature independent chloroform clad-filled photonic crystal fiber (PCF) for spectroscopic and soliton pulse applications. We have studied the nonlinearity and dispersion of the proposed PCF for various temperatures with different fiber parameters. By using the nonlinear Schrodinger equation (NLSE), we have analyzed the spectral output of the chloroform clad-filled PCF for different temperatures and compared the output spectra of the proposed PCF with conventional silica core PCF. The output spectral width is found to be invariant (0.1 nm/�C) with temperature variations (20 �C - 40 �C) for a cladding capillary diameter value of 4 �m. The same chloroform clad-filled photonic crystal fiber provides high stability for soliton pulses against temperature variations. The proposed PCF model can find applications where we need temperature independent spectral output and soliton pulse communications. � 2022 Elsevier GmbH
