Abstract

We have experimentally demonstrated a cation and anion sensor by using short linear photonic crystal microcavities with an embedded quantum dot active region. The photonic crystal microcavity covered with an ion-selective polymer forms a submicrometer optical detection system sensitive to small changes of perchlorate anion $\left(\mathrm{Cl}\mathrm{O}_4{}^{-}\right)$ and calcium cation $\left({\mathrm{Ca}}^{2+}\right)$ concentrations.
