Nanophotonic is considered an emerging technology for future many-core systems due to its potentials for low-power and high-bandwidth communications. Nevertheless, challenges such as crosstalk noise and temperature variation of photonic devices significantly reduce the optical signal-to-noise ratio which leads to reliability decrease in the optical network on chips. In this paper, we propose a thermally-tuned symmetric optical switch (TTSOS) and analyze its thermal effects. Using thermal-based adjustment in this design leads to reduce power loss under temperature variation. The functionality of the switch is examined through several numerical simulations with 10Gb/s non-return-to-zero signals. The simulation results show the data transmissions at 10Gb/s with low crosstalk and power penalty less than −50 dB and 0.1 dB, at $1.1\times 10^{-31}$ bit error rate, respectively. TTSOS improves the reliability in the resonant wavelength shift of micro-ring resonator, as well as the performance of the optical multi-stage networks. Finally, at the system-level, we systematically study the worst case as well as the average insertion loss in Benes-based optical network-on-chip.

纳米光子技术因其低功耗和高带宽通信的潜力而被认为是未来多核系统的新兴技术。然而，诸如串扰噪声和光子器件的温度变化之类的挑战显着降低了光信噪比，这导致芯片上光网络的可靠性下降。在本文中，我们提出了一种热调谐对称光开关（TTSOS）并分析了其热效应。在此设计中使用基于热的调节可减少温度变化下的功率损耗。通过对具有10Gb / s非归零信号的几个数值模拟进行了检查，以检查交换机的功能。仿真结果表明，在10Gb / s的数据传输速率下，串扰低，功率损耗分别小于−50 dB和0.1 dB。$\mathrm{1个}。\mathrm{1个}\times \mathrm{1个}{0}^{-31}$误码率分别。TTSOS改善了微环谐振器的谐振波长偏移的可靠性以及光学多级网络的性能。最后，在系统级，我们系统地研究了基于Benes的片上光网络的最坏情况以及平均插入损耗。
