“…In this case, the refractive index of an entire one-side of the bulky MMI waveguide was altered, which prohibited the ability for dual input switching. On other works, the power consumption of 2 × 2 polymer switches had been reduced down to 16 mW using fluorinated polyimide [10] and 12 mW using fluorinated polyether [11]. However, to achieve power consumptions below 10 mW remains to be a difficult task while switching response times linger in the few milliseconds range.…”

This paper analytically and experimentally investigates and compares the characteristics of two kinds of polymer buried-channel waveguide thermo-optic switches such as 1) a multimode interference (MMI) switch using a single MMI coupler and 2) a Mach-Zehnder interferometer (MZI) switch. Especially, the MZI switch experimentally exhibited low-power consumption of 3.5 mW, high-speed with a response time of less than 200 μs, polarization independence as well as in a wideband of about 80 nm. These low-power consumption, relatively high-speed, and polarizationindependent switching characteristics are almost coincident with the designed ones. Furthermore, an improved MZI structure is proposed for lower switching power consumption, and it is expected below 0.5 mW with an enhanced thermal localization structure.Index Terms-Mach-Zehnder interferometer, multi-mode interference, optical polymers, optical switches, thermo-optic effects.
