Ar的第三谱带260nm中心谱区光学腔效应的实验观察

采用强流相对论电子束横向抽运纯氩 ,在属于 Ar的第三谱带范围内的 2 6 0 nm的中心谱区观察到了光学腔效应 ,并指出同时具有陡前沿和强流相对论特点的电子束抽运是实现这一中心谱区光学腔效应的重要条件。

有机薄膜电致发光器件的光学微腔效应

制备了以铝掺杂氧化锌（ＡＺＯ）透明导电膜为阳极的有机薄膜电致发光微腔器件，研究了垂直的光学法布里－珀罗（Ｆａｂｒｙ－Ｐｅｒｏｔ）微共振腔对有机器件的自发发射的微腔效应。发现了光谱窄化、发光强度增加及发射的角度依赖关系等现象。具有微腔结构的器件发射谱半高宽只有１４ｎｍ，而非微腔器件在１００ｎｍ以上；微腔器件的峰高比非微腔的器件高一倍以上，微腔器件的发射峰随测量角的增大而“蓝移”。用ＴｉＯ２作填充调节层或用不同厚度的ＡＺＯ层来改变腔的光学厚度，得到了不同发光颜色。

Opto-Mechanical Effects in Superradiant Light Scattering by Bose-Einstein Condensate in an Optical Cavity

We investigate the effects of a movable mirror (cantilever) of an optical cavity on the superradiant light scattering from a Bose-Einstein condensate (BEC) in an optical lattice. We show that the mirror motion has a dynamic dispersive effect on the cavity-pump detuning. Varying the intensity of the pump beam, one can switch between the pure superradiant regime and the Bragg scattering regime. The mechanical frequency of the mirror strongly influences the time interval between two Bragg peaks. We find that when the system is in the resolved side band regime for mirror cooling, the superradiant scattering is enhanced due to coherent energy transfer from the mechanical mirror mode to the cavity field mode.
