摘要：
砷化镓光学谐振器已被认定为光与物质相互作用的平台，应用范围从光力学到涉及非线性光学的量子电动力学。本文提出一种直径5毫米的回音壁模式谐振器，由未掺杂砷化镓制成。其制备采用单点金刚石车削工艺，随后使用不同粒度的金刚石溶液进行抛光。经光学表征，所得谐振器的品质因数超过一百万。
英文摘要：
Gallium arsenide optical resonators have been identified as platforms for light-matter interactions ranging from optomechanics to quantum electrodynamics involving nonlinear optics. Here, we present a 5-mm-diameter whispering gallery mode resonator made of undoped gallium arsenide. The fabrication was done using single-point diamond turning followed by polishing with diamond solutions of varying grain size. The resulting resonator was optically characterized to have a quality factor of more than a million.
