This study presents high-order filter synthesis using micro-ring resonators and experimentally demonstrates filters up to the 11th order. Using a vernier architecture with polarization diversity, a widely tunable WDM filter based on 3rd-order micro-ring resonators is also demonstrated.

Dielectric resonators and filters
IEEE Microwave Magazine, 2007High-performance DRs and filters are widely used in wireless and satellite communication systems due to their superior characteristics, such as high unloaded Q, excellent temperature stability, and smaller size compared to their air-filled counterpart.

Dielectric filters fills gap between microstrip and cavity filters. Unfortunately they have huge disadvantage, concerning spurious transmission out of band. In this paper some investigation towards spurious reduction was done. Perfect conducting inserts to resonators was tested to achieve the selected objective.

Proceedings of the IRE, 1949
This paper describes a class of microwave filters in which input and output waveguides are connected by a number of resonators, each coupled directly to both guides. Signal components of different frequencies can pass from the input to the output largely through different resonators. This type of filter is a realization of a lattice network.

Acoustic electromechanical resonance filters
Sensors and Actuators A: Physical, 2002A mechanical resonator is used as the basis of an acoustically excited filter. The resonator, which is essentially a simple brass, reed-like structure, is located in a magnetic field generated by a permanent magnet. In the presence of a sound field, the mechanical resonator is excited and its motion is detected by measuring the induced voltage across ...

Proceedings of the IEEE, 1970
A solid-state adaptive (analog storage) device with stable electrical characteristics is described and demonstrated. The device is a resonant bandpass electronic filter with adaptable voltage gain; that is, the voltage gain-frequency transfer characteristic can be "set" to different values of attenuation by the application of an adapt signal and will ...

This chapter is concerned with the theory of the design of filters using resonators which are constructed using low loss high permittivity ceramics. Initially the fundamentals of modes in dielectric rod waveguides are discussed. An example of a filter using these resonators is presented.

Microring resonator notch filters
Conference on Lasers and Electro-Optics (CLEO 2000). Technical Digest. Postconference Edition. TOPS Vol.39 (IEEE Cat. No.00CH37088), 2000Summary form only given. Compact microring resonators are versatile devices which may become the basic building blocks of very large scale integrated photonic circuits. An important function which has been demonstrated with these resonators is spectral filtering. All filters made to date are of the all-poles type.

It is noted that a commercially available noise filter does not always represent the attenuation characteristics shown in the catalog, but sometimes magnifies the noise voltage when the filter is applied between the AC power cable and the equipment.
