摘要：
An electrochemically fabricated 1D photonic crystal of porous Si displaying a single reflectance peak is coupled to an optical fiber and embedded in activated carbon to sense the breakthrough of organic vapors (see figure). The sensor responds to various organic vapors, demonstrating filter end-of-service-life applications.
