Abstract

We propose a simple and low-cost solution for tracking the frequency of WDM channels, based on the thermo-optic tuning of Fabry-Perot silicon optical filters. The fabricated structures exhibit, due to a suitable coating stack on both cavity sides, high finesse and narrow bandwidth. Moreover, the free spectral range is large compared to the channel spacing, allowing the monitoring of one carrier frequency at a time. By means of a heater we change the cavity refractive index and move the transmission peaks, thus scanning the WDM frequency set. In particular, in a preliminary prototype realized by using a 100-/spl mu/m-long silicon cavity we demonstrate the possibility to resolve up to seven 50-GHz-spaced channels, with a crosstalk of -10 dB, at wavelengths around 1550 nm. More channels are easily resolvable by using shorter cavities.

简单和低成本的硅法布里-珀罗滤波器用于WDM信道监控

我们提出了一个简单和低成本的解决方案，用于跟踪WDM信道的频率，基于法布里-珀罗硅光滤波器的热光调谐。由于在腔体两侧有合适的涂层堆叠，所制备的结构具有高精细度和窄带宽。此外，与信道间距相比，自由频谱范围很大，允许一次监测一个载波频率。通过加热器改变腔体折射率，移动透射峰，从而对波分复用频率集进行扫描。特别是，在使用100-/spl μ m /m长的硅腔实现的初步原型中，我们展示了在波长约为1550 nm的情况下，解析多达7个间隔为50 ghz的通道，串扰为-10 dB的可能性。通过使用更短的空腔，可以很容易地解决更多的通道。
