Modelling and Characterization of Guiding Micro-structured Devices for Integrated Optics

, 2008
In this thesis we show several modelling tools which are used to study nonlinear photonic band-gap structures and microcavities. First of all a nonlinear CMT and BPM were implemented to test the propagation of spatial solitons in a periodic device ...

Asymmetrical Cross-Polarization Coupling in a Whispering-Gallery Microresonator

Photonics
Cross-polarization coupling between transverse electric (TE) and transverse magnetic (TM) whispering-gallery modes in an optical microresonator produces effects such as coupled-mode induced transparency (CMIT).

Whispering gallery modes enhance the near-infrared photoresponse of hourglass-shaped silicon nanowire photodiodes

, 2019
Silicon photodiodes are widely used in applications that require the measurement of the intensity, colour and position of visible light. Silicon is an attractive material for these systems owing to its low cost, low noise, and easy on-chip integration ...

Influence of the distributed coupling of a waveguide with a disk dielectric resonator with whispering-gallery oscillations on its amplitude-frequency response

Физика волновых процессов и радиотехнические системы, 2015
The difference between the spectrum of forced oscillations of disk dielectric resonators (when distributed coupling with dielectric waveguide is used) and eigen oscillations of such resonator is considered.

Neodymium Photoluminescence in Whispering Gallery Modes of Toroidal Microcavities.

, 2006
We report on light emission from high-Q neodymium-implanted silica microtoroids. After description of the fabrication process of microtoroids, Neodymium light emission is analysed. This emission is coupled to various modes of the cavity. Using evanescent

A simplified way to manufacture high-Q microfiber coil resonators by controlling the input/output coupling

, 2007
The dependence of the Q-factor of the microfiber coil resonator on different input/output couplings is investigated and compared. A method of slowly varying input/output coupling is presented to considerably simplify the fabrication of high-Q ...
