Based on the analysis of the single-ring resonator, both the transfer functions of parallel-coupled structure and the ones of series-parallel structure in multiple-ring high order resonators are derived using the transfer matrix method. And the influences of the length of straight waveguide between rings, coupling coefficients between rings, coupling coefficient between straight waveguides and ring, the number of rings and the radii of rings on spectral response are also analyzed. Spectral response at drop channel with maximally flat response pass bands and sharper roll-off could be achieved by optimizing these parameters, so as to improve the performance of output spectral response.

The gaseous impurities in the alloys were well controlled with the sum of C, N and O less than 500wppm. For the first time it was found the strong interaction between Cr-Ti-CON, which reduces the mobility of Ti and CON, enhancing high-temperature strength and the aging-hardening property, and keeping the cold-work induced hardening at higher temperature. Aging-hardening could increase the tensile strength of V-4Cr-4Ti by 30% and could be utilized at 00 C for better economical performane of a vanadium structure. Hydrogen release will occur for the alloys tensile loaded at room temperature, which will affect the safety of a vanadium structure due to the resulting dimensional instability. For hydrogen embrittlement, impact toughness and fracture toughness of the alloy showed higher sensitivity than the tensile test elongation,so the toughness should be used as a new standard for the assessment of the embrittlement. Vanadium alloys were easily oxidized in air.
