An optical spectrum analyzer (OSA) is indispensable for research in optics and photonics. Typical OSAs are based on diffraction gratings, yielding a resolution of about 1 GHz. This resolution level is insufficient for two measurements that are key to our research: 1) distorted spectra of extremely high bit rate communications and 2) radio frequency transmissions on an optical carrier. We must observe, diagnose, and manipulate the optical spectra with higher accuracy and finer granularity than standard OSAs provide. To meet these measurement challenges in our research program, we request funding for a high-resolution optical spectrum analyzer (HR-OSA).

光谱分析仪（OSA）是光学和光子学研究中不可缺少的仪器。典型的OSA基于衍射光栅，产生约1 GHz的分辨率。这种分辨率水平对于我们研究的两个关键测量是不够的：1）极高比特率通信的失真频谱和2）光载波上的射频传输。我们必须以比标准OSA提供的更高的精度和更精细的粒度来观察、诊断和操纵光谱。为了满足我们的研究计划中的这些测量挑战，我们要求资助高分辨率光谱分析仪（HR-OSA）。
