我们给出了从光子晶体光波导上激光图案化SU-8光刻胶条获得的光子分子的实验和数值研究。研究了由单条定义的腔的性质，证明了光波导上的两个相邻条形成一对光耦合腔。模拟结果和显微光致发光图谱测量表明，耦合强度可以通过控制条带之间的间距来调节。利用共焦解耦合的收集点和激发点的映射来显式地显示光子分子两个腔之间的耦合。
We present experimental and numerical investigations of photonic molecules obtained from laser patterned SU-8 photoresist strips on photonic crystal waveguides. Properties of cavities defined by a single strip are investigated and we show that two adjacent strips on a waveguide form a pair of optically coupled cavities. Simulation results and micro-photoluminescence mapping measurements demonstrate that the coupling strength is tunable by controlling the separation between the strips. Confocal mapping with decoupled collection and excitation points is used to explicitly show coupling between two cavities of a photonic molecule.
