چکیده انگلیسی
Universal structure and thorough analysis were proposed for a kind of polymer optical switch using N-th order microring resonator side-coupled Mach-Zehnder interferometer (MRR-SC-MZI). Formulation and expression of output power, insertion loss and crosstalk were derived, and detailed design and optimization were carried out. Analytical results indicate that all devices for Nâ¥1 can perform normal switching function, and 8â¥Nâ¥2 is preferred for dropping the driving voltage below 5 V. For the seven MRR-SC-MZI EO switches (N=2-8) whose cross-state voltages are within 0-2.32 V, their bar-state voltages are within 0.96-4.83 V and their insertion losses are within 0.35-0.85 dB at bar state, whereas those within 0.14-1.70 dB at cross state; their crosstalk are within â20.79 to â31.11 dB at bar state, whereas those are within â13.86 to â20.36 dB at cross state; their 3-dB electrical bandwidths are within 18.5-28.0 GHz, and 3-dB optical bandwidths for the two output ports are within 18.1-40.0 GHz and 32.0~55 GHz, respectively. Comparison indicates that the driving voltages of the proposed MRR-SC-MZI switching devices are 10-250 times smaller than those of the traditional MZI EO switches with the same EO region length, device length and structural parameters. Therefore, due to small footprint size and low driving voltage, this switching configuration can be densely integrated onto optoelectronic chips.
