摘要:

研究了InP基平面光子晶体微腔在1550 nm短脉冲激发下的三维局域光子模的二次谐波和和频混频现象。支持两个紧密间隔模式的三个缺失孔微腔表现出丰富的二阶散射光谱,其反映了在宽带共振脉冲激发后的衰荡期间经由体InP χ(2)的模内和模间混合。与非共振源的同时激发导致来自微腔的可调谐二阶辐射。

英文摘要:

Second-harmonic and sum-frequency mixing phenomena associated with 3D-localized photonic modes are studied in InP-based planar photonic crystal microcavities excited by short-pulse radiation near 1550 nm. Three-missing-hole microcavities that support two closely-spaced modes exhibit rich second-order scattering spectra that reflect intra- and inter-mode mixing via the bulk InP chi(2) during ring-down after excitation by the broadband, resonant pulse. Simultaneous excitation with a non-resonant source results in tunable second-order radiation from the microcavity.
