Described herein are systems and methods for performing optical signal analysis and lesion predictions in ablations. A system includes a catheter coupled to a plurality of optical fibers via a connector that interfaces with a computing device. The computing device includes a memory and a processor configured to receive optical measurement data of a portion of tissue from the catheter. The processor identifies one or more optical properties of the portion of tissue by analyzing the optical measurement data and determines a time of denaturation of the portion of tissue based on the one or more optical properties. A model is created to represent a correlation between lesion depths and ablation times using the time of denaturation, the one or more optical properties, and the predetermined period of time. A predicted lesion depth for a predetermined ablation time is generated using the model.
