On Chip

A new method of permittivity measurement based on the on-chip coplanar waveguide (CPW) with finite metal thickness without close box or microfluid channel is presented in this paper. The material under test (MUT) is directly located in the slot line of the CPW which is considered to be the strongest field distribution area. The proposed structure sample is simulated through HFSS. The simulation results agree well especially when the metal thickness is comparable with the slot line width, the errors are less than 5%.

Disperse Red 1

Polymeric Disperse Red 1 (DR1)/SU-8 electro-optic (EO) switch incorporating inverted-rib waveguide structure is designed and fabricated by all-wet etching process. The guest-host EO material DR1/SU-8 has been successfully synthetized and its optical properties are characterized in detail. The DR1/SU-8 material presents a low processing cost, an excellent photostability and a large EO coefficient of 15.4 pm/V. The characteristic parameters of both the inverted-rib waveguide and the coplanar waveguide electrodes are carefully designed and simulated. By all-wet etching process, the optimized Mach–Zehnder interferometer switch is successfully fabricated with a lower fiber-to-fiber insertion loss of 9.6 dB. The switch rise time and fall time are 322 ns and 294 ns, respectively.

The possibility of computer modeling implementation of electrically controlled magnetoelectric (ME) microwave devices is considered. The computer modeling results of different structures of ME microwave devices based on layered ferrite-piezoelectric structure formed on the slot line, microstrip line and coplanar waveguide are offered. Results are reported as frequency dependencies of insertion losses of ME devices.
