  • [IEEE 2018 19th International Conference on Electronic Packaging Technology (ICEPT) - Shanghai (2018.8.8-2018.8.11)] 2018 19th International Conference on Electronic Packaging Technology (ICEPT) - Thermal analysis and optimization of air trench structures for thermally tunable devices

    摘要： Thermally tunable devices are important building blocks of photonic integrated circuits for optical fiber communication and sensing applications. To increase their tuning efficiency, an air trench structure has been introduced to the devices. By using finite element method, the distributions of temperature, stress and displacement of the waveguide are studied. After optimization, under the temperature rise of 70 oC, the maximum values of temperature difference, stress and displacement are smaller than 10% of the temperature rise, allowable stress and 0.002% of the waveguide length, respectively. This optimized air trench structure is desired for thermally tunable devices reaching low power consumption, high temperature uniformity and mechanical stability.

  • Thermal design management of highly mechanically stable wavelength shifter using photonic crystal waveguide

    摘要： A thermally tunable device based on photonic crystal waveguide integrated with the micro-hotplate on its surface is proposed. A design strategy for modelling of temperature and stress in the MHP is investigated for providing robustness and high mechanical stability in the reconfigurable device. The required temperature is obtained under stress elongation fatigue limit for thermal tuning applications in optical devices. The performance parameters like confinement factor, wavelength transfer coefficient and extinction ratio are obtained as 78.2%, 0.086 nm/K and 30.04 dB respectively with an excess loss of only 0.20 dB. The response-time in the optimized device is 12 μs for achieving the switching spectral shift of 26 nm in the transmission spectrum of PCW. The reconfigurable device platform offers a great potential for wide range of tuning in switches and filters applications
