半導體光學在應用上是諸多光電元件的基石，其包羅萬象的材料光電特性，其實反映的是光(Light)與物質(Matter)交互作用的結果，這些光學表徵建構在半導體激子、聲子及共振腔光子間的動力學行為上。本實驗室將運用不同能隙與不同量子侷限效應的發光半導體材料(從塊材、二維材料到量子點等)，搭配多樣的光交互作用平台(如共振腔或超穎光學介面等)，進而研究其中半導體光學的原理知識，並且提出調變的手法與技術。於此過程中，我們將透過模擬軟體輔助元件設計，搭建各類光譜分析光路及光源(含超快雷射等)與低溫系統(液態氮為主要)，最終驗證半導體材料或元件的諸多光學響應，如半導體雷射閥值、增益、發光偏振態、介電係數響應、熱光係數、拉比分裂能等等。誠摯歡迎對此有興趣的朋友們加入我們，或與我們分享你對該領域的心得與知識！
Semiconductor Optics serves as the foundation for a wide range of optoelectronic devices. The diverse optoelectronic characteristics of these materials fundamentally reflect the interaction between light and matter. Our laboratory conducts research along these two central themes: the use of light-emitting semiconductor materials with varying bandgaps and quantum confinement effects, including bulk materials, two-dimensional materials, and quantum dots, and the integration of various light–matter interaction platforms, such as optical resonators and metasurfaces. Through these efforts, we aim to explore the underlying physical principles and develop novel modulation techniques. To support this research, we utilize simulation software for device design, construct customized optical spectroscopy setups, and employ cryogenic systems to investigate the optical responses of materials and devices. Welcome those interested in this field to join our team or share your insights and experiences with us!

◆ The (PEA)2PbBr4 perovskite microplates can be regarded as a simple resonator. We adopted the temperature-dependent reflectance to extract thermal-optic coefficients, 2D exciton binding energies, and 2D exciton state, etc.

◆ The cross-section of a ZnO microrod shows the hexagonal geometry. We investigated the strong coupling behaviors between bulk excitons and cavity photons. The curvatures shown in the angle-resolved photoluminescence spectroscopy reflect the dielectric responses due to the exciton-photon interactions.
