In this thesis work, amorphous photonic materials, which are an alternative to photonic crystals and offering flexibility and comparable performance, are designed for photonic integrated circuits and analyzed. A design guideline is presented for the first time with experimental verification in telecommunication wavelengths. Amorphous photonic materials are artificially designed materials that possessing random refractive index distributions and has photonic band gaps due to the inherent short-range order. For the amorphous photonic materials, a Monte Carlo method is proposed which is taking natural crystalline-amorphous semiconductor transitions as an example and the affecting design parameters are analyzed. The generated amorphous structures are analyzed numerically and experimentally for verification. Furthermore, the factors affecting band gap is scrutinized. The band gap asymmetry which is one of the basic properties of amorphous photonic materials are explained theoretically, with the help of electronic amorphous semiconductors.
