“…1(a). The MZI based optical switches have been demonstrated with low-power consumption, fast response times, stable thermal performance and high fabrication tolerances at the near-infrared wavelengths, which are also expected for our devices designed for the 2-μm wave band [20]. Although the microring resonators (MRRs) usually exhibited a lower power consumption and smaller footprint [21], limited operation bandwidth and high temperature sensitivity will hinder its practical use for the optical switch.…”

The 2-μm spectral window is emerging as a promising candidate for the next generation communication. We present a 2 × 2 Mach-Zehnder interferometric thermo-optic switch at 2-μm waveband. The device is fabricated on a 220 nm thick silicon-on-insulator wafer with standard complementary metal oxide semiconductor (CMOS) process. We demonstrate an over 30 dB extinction ratio under the power consumption of 32.3 mW, with an average switching time of ∼15 μs. This proof of principle optical switch paves a way toward full silicon-based chip-scale interconnects in the 2-μm waveband.

“…The thermal optical switch can be divided into Mach-Zehnder (M-Z) thermal optical switch, multimode-interference (MMI) thermal optical switch, X-band thermal optical switch, and digital thermal optical switch [12,13,14]. M-Z optical switch has large process tolerance and lower power consumption.…”

Polymer thermal optical switches have low power consumption and 532 nm is the communication window of polymer fiber. Polymer thermal optical switches at 532 nm are rarely reported, because of switching extinction ratio properties that are restricted by modes of the waveguide. Single mode waveguide at 532 nm is hard to fabricate due to the dissolution of core and cladding materials. A polymer M-Z thermal optical switch at 532 nm was first demonstrated based on the wet etching method. The proposed thermal optical switch was consisted of silica substrate, photosensitive polymer core, and cladding material. The device was fabricated and tested with the power consumption of 6.55mW, extinction of 4.8 dB, and switching time of 0.23 ms (rise)/0.28 ms (down). An optimized switch structure combining with the UV-writing technique and graphene thermal conduction layer was proposed based on the experiments above. A side electrode was designed to reduce the power consumption and the switching time. The optimized device was calculated to have a power consumption of 1.5 mW. The switching time of the UV-writing device was simulated to be 18.2 μs (rise) and 85 μs (down). The device is promising in the wearable device and laser radar area.

“…Many researches on the polymer waveguide MMI coupler have been carried out [23][24][25][26][27][28], which are generally around 1550 nm.

A 2×2 optical waveguide coupler at 850 nm based on the multimode interference (MMI) structure with the polysilsesquioxanes liquid series (PSQ-Ls) polymer material and the imprint technique is presented. The influence of the structural parameters, such as the single mode condition, the waveguide spacing of input/output ports, and the width and length of the multimode waveguide, on the optical splitting performance including the excess loss and the uniformity is simulated by the beam propagation method. By inserting a taper section of isosceles trapezoid between the single mode and multimode waveguides, the optimized structural parameters for low excess loss and high uniformity are obtained with the excess loss of -0.040 dB and the uniformity of -0.007 dB. The effect of the structure deviations induced during the imprint process on the optical splitting performance at different residual layer thicknesses is also investigated. The analysis results provide useful instructions for the waveguide device fabrication.
