Abstract

A compound cavity was proposed to achieve both whispering gallery mode (WGM) lasing and random lasing. The WGM-random compound cavity consisted of a random structure with an annular boundary, which was fabricated by a method combining both inkjet printing and metal-assisted chemical etching methods. An ultrathin polymer membrane was attached to the WGM-random compound cavity, forming a polymer laser device. A transformation from WGM lasing to random lasing was observed under optical pumping conditions. The laser performance could be easily tailored by changing the parameter of the WGM-random compound cavity. These results provide a new avenue for the design of integrated light sources for sensing applications.

摘要

提出了一种复合腔，以实现回音壁模式（WGM）激光和随机激光。WGM-随机复合腔由具有环形边界的随机结构组成，该结构通过喷墨打印和金属辅助化学蚀刻方法相结合的方式制造。将超薄聚合物膜附着到WGM-随机复合腔上，形成聚合物激光器件。在光泵浦条件下观察到了从WGM激光到随机激光的转变。通过改变WGM-随机复合腔的参数，可以轻松调整激光性能。这些结果为用于传感应用的集成光源设计提供了一条新途径。
