Types of brain lesions, tumors, and cancers are still considered deadly. They require accurate and expensive detecting, diagnosing, and treatment methods. This work presents a biomedical photonic-based sensor that can detect and distinguish accurately between normal and abnormal brain tissues. The abnormal ones consist of lesions, tumors, and cancerous tissues. The designed sensor detects these types with acceptable sensitivity and high-quality factor compared to other photonic-based detecting techniques. The proposed sensor achieves a sensitivity of 1332 nm/RIU, a very low detection limit of 9.08 × 10-6, and an ultra-high quality factor of 16254. Ultra-compactness and the ability to fabricate with today's technology are novel features in the proposed design. An abbreviated review of non-optical detection techniques is presented. An in-depth comparison between this work and related photonic-based recent literature is drawn to validate the efficacy and authenticity of the proposed design.
