频率、消光比和带宽可调的八通道可重构微带滤波器
Eight-channel reconfigurable microring filters with tunable frequency, extinction ratio and bandwidth
摘要：
我们展示了一个八通道可重构的光滤波器的硅芯片组成的级联微谐振器和集成紧凑的加热器。嵌入式马赫-曾德尔（MZ）臂耦合到微波谐振器，滤波器的重要参数，如中心频率，消光比和带宽，可以同时控制的目的，过滤，路由和频谱整形，从而使我们的方法在密集波分复用（DWDM）和射频任意波形产生（RFAWG）的潜在有用的。多通道滤波器响应被成功地调整到与国际电信单位（ITU）网格相匹配，信道间隔为50、100和200 GHz。通过对MZ臂进行加热，实现了可编程通道选择性，并实现了通过端口消光比从0 dB到27 dB的连续调节。同时，由于加热，分出端口的3dB带宽从0.11nm变化到0.15nm。该器件具有超紧凑的基底面（1200μ mx 100 μm），不包括金属引线和接触焊盘，使其适合大规模集成。
英文摘要：
We demonstrate an eight-channel reconfigurable optical filter on a silicon chip consisting of cascaded microring resonators and integrated compact heaters. With an embedded Mach-Zehnder (MZ) arm coupling to a microring resonator, the important parameters of a filter such as center frequency, extinction ratio and bandwidth can be controlled simultaneously for purposes of filtering, routing and spectral shaping, thus making our method potentially useful in dense wavelength division multiplexing (DWDM) and radio frequency arbitrary waveform generation (RFAWG). Multichannel filter response was successfully tuned to match the International Telecommunication Unit (ITU) grid with 50, 100 and 200GHz in channel spacing. Programmable channel selectivity was demonstrated by heating the MZ arm, and continuous adjustment of through-port extinction ratio from 0dB to 27dB was achieved. Meanwhile, the 3dB bandwidth in the drop port changed from 0.11nm to 0.15nm due to the heating. The device had an ultra-compact footprint (1200μmx100μm) excluding the metal leads and contact pads, making it suitable for large scale integration.
