We present an InP monolithically integrated wavelength selector that implements a binary search for selecting N modulated wavelengths. The wavelength selector filter is realized using log(2)N an active Mach-Zehnder interferometer filter and broadband optical gating elements. Nanosecond reconfigurable operation with a spectral-alignment over 3.2 nm free spectral range is achieved with an extinction ratio exceeding 25 dB. Error-free operation of the wavelength selector for four modulated wavelengths with 2 dB of power penalty is demonstrated.
我们展示了一种磷化铟单片集成波长选择器，它通过二分搜索来选择N个调制波长。该波长选择器滤波器是利用log(2)N个有源马赫-曾德尔干涉仪滤波器和宽带光门控元件实现的。在超过3.2纳米的自由光谱范围内实现了具有光谱对准的纳秒级可重构操作，消光比超过25分贝。展示了该波长选择器在四个调制波长下无差错运行，功率代价为2分贝。
