论文摘要
我们引入了一个热光相变（TOPS）阵列结构，具有每个相位变速器的独立相位控制，用于具有两个不同的控制方案的大规模和高密度光子积分电路：脉冲振幅调制（PAM）和脉冲宽度调制（PWM）。我们意识到了紧凑的螺旋顶和288个元素的高密度行圆顶阵列阵列，并具有该体系结构，并驱动顶部具有控制方案和不同阵列尺寸的波形。我们提出了一个热激发模型和一个有限差异方法的模拟，以模拟大规模顶部阵列，并通过实验和理论上进行比较。我们还分析了在已实现的顶部阵列中热串扰的影响，并与开发的模型实现了热串扰校正算法。高密度顶部阵列结构和热串扰校正算法为高密度顶部阵列铺平了具有独立相位控制的高度光子积分电路的道路，这些电路与电子设备有限的电压摆动和带宽相连。
We introduce a thermo-optic phase shifter (TOPS) array architecture with independent phase control of each phase shifter for large-scale and high-density photonic integrated circuits with two different control schemes: pulse amplitude modulation (PAM) and pulse width modulation (PWM). We realize a compact spiral TOPS and a 288-element high-density row-column TOPS array with this architecture and drive TOPS with waveforms of both control schemes and of different array sizes. We present a thermal excitation model and a finite difference method-based simulation to simulate large-scale TOPS arrays and compare both schemes experimentally and theoretically. We also analyze the effects of thermal crosstalk in the realized TOPS array and implement a thermal crosstalk correction algorithm with the developed model. The high-density TOPS array architecture and the thermal crosstalk correction algorithm pave the way for high-density TOPS arrays with independent phase control in large-scale photonic integrated circuits interfaced with electronics limited in voltage swing and bandwidth.
