Thetransmission characteristics are analyzed, and the general formulas of the transmission functions are presented for the microring resonant wavelength multiplexer (MRRWM) with 1×N channels in terms of the coupled mode theory.

In this paper,a micro-ring resonant filter(MRRF),consisting of two cascaded coupled racetrack rings and using MMI as input/output coupling structure,was designed and fabricated on the Si substrate by using a UV sensitive polymer material SU-8 as the core material of the waveguide and polymer material CYTOP as the bottom cladding layer.

Fabrication process,structure and its effect on parameters of low temperature co-fired chip ceramic microwave resonators were presented.

Fabrication process, structure and its effect on parameters of chip multilayer ceramic microwave resonators were presented.

A practical method of measuring microwave resonator unloaded Q-factor is presented,which could eliminate phase shift of feed line when Q-factor is estimated by critical-points method.
