Voltage-tunable optical parametric oscillator with an alternating dispersion dimer integrated on chip

With this commit we present or theoretical and experimental data together with plotting codes for our manuscript entitled "Voltage-tunable optical parametric oscillator with an alternating dispersion dimer integrated on chip". Optical parametric oscillators enable the conversion of pump light to new frequency bands using nonlinear optical processes. Recent advances in integrated nonlinear photonics have led to the creation of compact, chip-scale sources via Kerr nonlinearity-induced parametric oscillations. While these sources have provided broadband wavelength tuning, the ability to tune the emission wavelength via dynamically altering the dispersion, has not been attained so far. Here we present a voltage-tunable, on-chip integrated optical parametric oscillator based on an alternating-dispersion dimer, allowing us to tune the emission over nearly 20 THz near 1550 nm. Unlike previous approaches, our device eliminates the need for a widely tunable pump laser source and provides efficient pump filtering at the drop port of the auxiliary ring. Integration of this scheme on a chip opens up the possibility of compact and low-cost voltage-tunable parametric oscillators with diverse application possibilities.本次版本提交随附题为《片上集成交替色散二聚体的电压可调光参量振荡器》的论文稿件的理论与实验数据，以及绘图代码。光参量振荡器（optical parametric oscillator）可通过非线性光学过程，将泵浦光转换至新的频段。近年来，集成非线性光子学领域的研究进展借助克尔（Kerr）非线性诱导的参量振荡，成功研制出紧凑的片上尺度光源。尽管此类光源已实现宽带波长调谐，但目前仍无法通过动态改变色散来调控发射波长。本文提出一款基于交替色散二聚体的电压可调片上集成光参量振荡器，可在1550 nm波段附近实现近20太赫兹（THz）的发射波长调谐范围。与既往研究方案不同，本器件无需使用宽调谐泵浦激光器，且可在辅助环的下路端口（drop port）实现高效的泵浦光滤波。将该方案集成于芯片之上，有望研制出紧凑、低成本的电压可调光参量振荡器，具备多样的应用潜力。
