We demonstrate the first W-band optoelectronic oscillator (OEO), that oscillates at 94.5 GHz with a measured single side band (SSB) phase noise of −101 dBc/Hz at an offset frequency of 10 kHz from the carrier. Side mode suppression of more than 65 dB has been achieved by using injection locking. This OEO has potential application as a signal source in emerging W-band applications (e.g. fiber-wireless links) and opens a path to low phase noise sources beyond 100 GHz.

W波段光电振荡器

我们展示了第一个 W 波段光电振荡器 (OEO)，它以 94.5 GHz 的频率振荡，测量的单边带 (SSB) 相位噪声为 -101 dBc/Hz，与载波的偏移频率为 10 kHz。通过使用注入锁定已实现超过 65 dB 的边模抑制。这种 OEO 具有作为新兴 W 波段应用（例如光纤无线链路）中的信号源的潜在应用，并为 100 GHz 以上的低相位噪声源开辟了道路。
