Novel Nonreciprocal Devices with Integrated Electromagnet for Silicon Photonics
We present a novel approach to construct integrated isolators and circulators based on magneto-optical materials. An integrated electromagnet is designed and fabricated, eliminating the need for a permanent magnet. The fabricated devices exhibit high performance and can be easily integrated/packaged. Introduction Nonreciprocal components, such as optical isolators and circulators, are fundament...
متن کاملCanonical Transformations, Entropy and Quantization
This paper considers various aspects of the canonical coordinate transformations in a complex phase space. The main result is given by two theorems which describe two special families of mappings between integrable Hamiltonian systems. The generating function of these transformations is determined by the entropy and a second arbitrary function which we take to be the energy function. For simple...
متن کاملComment on "Nonreciprocal light propagation in a silicon photonic circuit".
We show that the structure demonstrated by Feng et al. (Reports, 5 August 2011, p. 729) cannot enable optical isolation because it possesses a symmetric scattering matrix. Moreover, one cannot construct an optical isolator by incorporating this structure into any system as long as the system is linear and time-independent and is described by materials with a scalar dielectric function.
متن کاملImpenetrable Barriers and Canonical Quantization
We address a conceptual issue of reconciling the traditional canonical quantization framework of quantum theory with the spatially restricted quantum dynamics and the related spectral problems for confined and global observables of the quantum system.
متن کاملCanonical quantization and expanding metrics
The canonical formalism for expanding metrics scenarios is presented. Nonunitary time evolution implied by expanding geometry is described as a trajectory over unitarily inequivalent representations at different times of the canonical commutation relations. Thermal properties of inflating Universe are also discussed. PACS: 04.60.d, 98.80.c In this paper we study the quantum field theory (QFT) f...
