Temperature dependence of the spectral characteristics of distributed-feedback resonators.
We characterize the spectral response of a distributed-feedback resonator when subject to a thermal chirp. An Al2O3 rib waveguide with a corrugated surface Bragg grating inscribed into its SiO2 top cladding is experimentally investigated. We induce a near-to-linear temperature gradient along the resonator, leading to a similar variation of the grating period, and characterize its spectral respo...
متن کاملTemperature dependence of I-V characteristics of C60 molecule
Making use of a generalized Green’s function technique and Landauer formalism, the temperature depended current-voltage (I-V) characteristics of C60 molecule, sandwiched between two metallic electrodes are numerically investigated. In addition, the influence of the electron-phonon coupling strength on the electronic properties of the molecule is studied. The I-V characteristics of the molecule ...

متن کاملSpectral engineering of the transmission characteristics of racetrack resonators
Integrated whispering gallery mode resonators constitute a family of compact devices which has been shown to be attractive to perform selective filtering, low-threshold emission or nonlinear conversion functions [1]. In the latter case, and for Kerr frequency comb generation in particular, the performance is controlled by the ability to achieve critical coupling over a wide spectral range. In t...
