15 صفحه اولQ factor measurements , analog and digital
1. Introduction Resonators are the basic building blocks of rf filters and oscillators. Like any other circuit component, a resonator must be experimentally tested to determine its properties. The three fundamental characteristics of an rf resonator that have to be determined by measurement are: (1) resonant frequency, (2) coupling coefficient, and (3) unloaded Q factor.
متن کاملOptimization of the Q Factor in Photonic Crystal Microcavities
We express the quality factor of a mode in terms of the Fourier transforms of its field components and prove that the reduction in radiation loss can be achieved by suppressing the mode’s wavevector components within the light cone. Although this is intuitively clear, our analytical proof gives us insight into how to achieve the factor optimization, without the mode delocalization. We focus on ...
متن کاملHigh Q-factor microring resonator wrapped by the curved waveguide
In this work, we study the performances of ring resonators of different type by analyzing the bending loss and the condition of the critical coupling. We propose that the bending loss of microring can be reduced by wrapping a concentrically curved waveguide. The difference of propagation constant between two concentrically curved waveguides can be tuned by adjusting the bus waveguide width to o...
متن کاملSparse signal representations using the tunable Q-factor wavelet transform
The tunable Q-factor wavelet transform (TQWT) is a fully-discrete wavelet transform for which the Q-factor, Q, of the underlying wavelet and the asymptotic redundancy (over-sampling rate), r, of the transform are easily and independently specified. In particular, the specified parameters Q and r can be real-valued. Therefore, by tuning Q, the oscillatory behavior of the wavelet can be chosen to...
