This proposal is a renewal for the award ECS-9421517, "Semiconductor Physics and Photonics". The PI has played a significant role in the pioneering work and made important discoveries regarding the normal-mode coupling in semiconductor microcavities. This renewal proposal is aimed to extend the previous accomplishment toward quantum limit of the micro-cavity where a strong coupling exists that can produce a change in the absorption by a single photon. All semiconductor microcavities to date have operated in the semi-classical regime where 105 photons are required. Although interesting optical non-linearity can be obtained in such a system, the quantum effects analogous to atomic cavity quantum electrodynamics has not been observed. In this proposal the PI suggests to fabricate and analyze transversely confined microcavities with ~100 nm diameters that will enable the quantum regime to be achieved in the semiconductor system.

该提案是ECS-9421517“半导体物理学和光子学”奖的延续。 PI在开创性工作中发挥了重要作用，并在半导体微腔中的简正模耦合方面取得了重要发现。 该更新建议旨在将先前的成就扩展到微腔的量子极限，其中存在强耦合，可以通过单个光子产生吸收的变化。 迄今为止，所有的半导体微腔都在半经典状态下工作，需要105个光子。 虽然在这样的系统中可以获得有趣的光学非线性，类似于原子腔量子电动力学的量子效应还没有被观察到。 在该提案中，PI建议制造和分析直径约为100 nm的横向受限微腔，这将使量子机制能够在半导体系统中实现。
