摘要

通过向电光梳状发生器注入27.5- 30ghz的扫描射频信号，提出了一种具有成本效益的可扩展测量范围的扫描技术。10阶谐波扫描在扩展范围(275-300 GHz)，其中超窄(Q >106)共振以亚mhz分辨率被很好地分辨。

Scalable Bandwidth and High-Precision Spectral Measurement by Frequency Chirped Comb

A cost-effective scan technique enabling scalable measurement range is presented by injecting a sweep RF signal of 27.5-30 GHz into an electro-optic comb generator. The 10th-order harmonic scans over an extended span (275-300 GHz) where an ultra-narrow (Q >106) resonance is well-resolved with sub-MHz resolution.
