Electro - Photonics
I introduce a new field: electro-photonics, where the best of the electronic and photonic technologies are combined to increase the capacity, flexibility and energy efficiency of communications systems. OCIS codes: (060.0060) Fiber optics and optical communications; (070.2025) Discrete optical signal processing; (130.0250) Optoelectronics; (130.3120) Integrated optics devices; (130.4110) Modula...
متن کاملTopological photonics
821 Frequency, wavevector, polarization and phase are degrees of freedom that are often used to describe a photonic system. Over the past few years, topology — a property of a photonic material that characterizes the quantized global behaviour of the wavefunctions on its entire dispersion band — has emerged as another indispensable degree of freedom, thus opening a path towards the discovery of...
متن کاملPhotonics Materials and Devices
Part 2 reviews the materials properties of photonic materials, such as structure (chemical bonds) and electrical conductivity (bands) in Group IV and III-V compound/alloy semiconductors. The correlation of the principal quantum number with optical, thermal and mechanical properties is examined. The definition of effective mass qualifies the energy-wavenumber dispersion relation for direct or in...
متن کاملMoore’s law in photonics
Similarities and differences between photonic and microelectronic integration technology are discussed and a vision of the development of photonic integration in the coming decade
متن کاملPlanar photonics with metasurfaces.
Metamaterials, or engineered materials with rationally designed, subwavelength-scale building blocks, allow us to control the behavior of physical fields in optical, microwave, radio, acoustic, heat transfer, and other applications with flexibility and performance that are unattainable with naturally available materials. In turn, metasurfaces-planar, ultrathin metamaterials-extend these capabil...
