"Central to this thesis is the characterisation and exploitation of electromagnetic properties of light in imaging and measurement systems. To this end an information theoretic approach is used to formulate a hitherto lacking, quantitative definition of polarisation resolution, and to establish fundamental precision limits in electromagnetic systems. Furthermore rigorous modelling tools are developed for propagation of arbitrary electromagnetic fields, including for example stochastic fields exhibiting properties such as partial polarisation, through high numerical aperture optics. Finally these ideas are applied to the development, characterisation and optimisation of a number of topical optical systems, polarisation imaging, multiplexed optical data storage, and single molecule measurements. The work has implications for all optical imaging systems where polarisation of light is of concern."

"This volume addresses recent developments in mathematical modeling in three areas of optical science: diffractive optics, photonic band gap structures, and waveguides. Particular emphasis is on the formulation of mathematical models and the design and analysis of new computational approaches. The book contains cutting-edge discourses on emerging technology in optics that provides significant challenges and opportunities for applied mathematicians, researchers, and engineers.Each of the three topics is presented through a series of survey papers to provide a broad overview focusing on the mathematical models. Chapters present model problems, physical principles, mathematical and computational approaches, and engineering applications corresponding to each of the three areas. Although some of the subject matter is classical, the topics presented are new and represent the latest developments in their respective fields."

"Fiber Optic Ring Resonator dapat digunakan sebagai sebuah sensor optik. Hal tersebut dilakukan dengan memanipulasi variabel – variabel yang mempengaruhi output persamaannya, yaitu panjang fiber L, intensitas rugi fraksional coupler γ!, koefisien coupling κ dan atenuasi amplitudo fiber α!. Variabel – variabel tersebut mempengaruhi parameter output berupa: FSR (Free Spectrum Range), FWHM (Full Width Half Maximum) dan F (Finesse). Dengan memanipulasi parameter output dari FORR, maka pengguna dapat menggunakannya sesuai kebutuhan sensor optik yang dibutuhkan.

"This thesis describes the first demonstration of a cooperative optical non-linearity based on Rydberg excitation. Whereas in conventional non-linear optics the non-linearity arises directly from the interaction between light and matter, in a cooperative process it is mediated by dipole-dipole interactions between light-induced excitations. For excitation to high Rydberg states where the electron is only weakly bound, the dipole-dipole interactions are extremely large and long range, enabling an enormous enhancement of the non-linear effect. Consequently, cooperative non-linear optics using Rydberg excitations opens a new era for quantum optics enabling large single photon non-linearity to be accessible in free space for the first time. The thesis describes the theoretical underpinnings of the non- linear effect, the pioneering experimental results and implications for experiments in the single photon regime."
