Abstract

In order to measure frequency responses of O/ E conversion devices such as photodiodes (PDs), we developed a measurement instrument named lightwave frequency response analyzer (LFRA). LFRA, which is based on a heterodyne technique utilizing an optical modulator, provides precise measurement solution with cost effective instrument. Measured results of two individual LFRAs show standard deviations less than 0.15 dB and maximum instrument difference less than 0.7 dB.
用于表征O/E转换装置的光波频响分析仪的研制
为了测量光电二极管等O/ E转换器件的频率响应,我们研制了光波频率响应分析仪(LFRA)。LFRA基于利用光调制器的外差技术,提供了具有成本效益的精确测量解决方案。两个lfra的测量结果表明,标准偏差小于0.15 dB,最大仪器差小于0.7 dB。
