Abstract

A photonic crystal is one of the most promising platforms for optical information processing as it can enable compact and efficient photonic devices and also their large scale integration on-chip. All-optical signal processing applications based on devices such as Semiconductor Optical Amplifier (SOA), nonlinear silicon waveguides, and quantum dots suffer from higher power consumption and lower bit rate when compared with Photonic crystal designs and structures.
One of the most promising technology in today’s sensing techniques and structures is the Photonic Crystal based sensors. This comes from the fact that is: they have nanometric sized defects and holes with very high operating sensitivity, especially to geometrical and physical changes.
In this thesis, a 2-D photonic crystal (PhC) based refractive index biomedical sensors are designed, simulated, and evaluated. All design process targets ultra-sensitive, ultra-quality factor, and compactness. The biomedical sensors proposed in this thesis used the cavity techniques. Three applications that are based on photonic crystals biomedical sensors are discussed (e.g., distinguish between different cancer cells, distinguish between famous types of blood components, and detect effective stages of Malaria). The results reflected on the three proposed designs achieve high sensitivity, high-quality factor, and compactness. Finite difference time domain and plane-wave expansion methods are used for analyzing these structures. These designs are suitable for detecting the diseases as mention before.
