Abstract: The fields of biological and medical physics have a particularly strong correlation with biomedical sensing applications. Our research aims to contribute into the optics of biomedical measurement using the selfmixing interferometry configuration through design and simulate SMI sensing system and more parameters have to be optimized. The performance was numerically investigated for the cases of changing important system parameters such as, external cavity length, external reflectivity and concentration of the target material. The next step in the optimized technique is its implementation in bio-sensing field. For the modified configuration, one can expect to have a strong correlation between the amplitude of the main peaks appearance and the glucose concentration. The time-delay of the system is correctly identified even in the presence of the reference light which enables us to extract the chaotic signature (glucose concentration) successfully. The numerical results find that the system can be used successfully as a biosensor.
