Abstract

We report the experimental implementation of a wireless transmission system with a 146-GHz carrier frequency which is generated by optical heterodyning the two modes from a monolithically integrated quantum dash dual-DFB source. The monolithic structure of the device and the inherent low noise characteristics of quantum dash gain material allow us to demonstrate the transmission of a 1 Gbps ON-OFF keyed data signal with the two wavelengths in a free-running state at 146-GHz carrier wave frequency. The tuning range of the device fully covers the W-band (75 - 110 GHz) and the F-band (90 - 140 GHz).

摘要

我们报告了一种无线传输系统的实验实现，该系统采用146GHz载波频率，由单片集成量子点双分布反馈源的两种模式进行光学外差产生。该器件的单片结构以及量子点增益材料固有的低噪声特性，使我们能够在146GHz载波频率下，以自由运行状态的两个波长演示1Gbps开关键控数据信号的传输。该器件的调谐范围完全覆盖了W波段（75 - 110GHz）和F波段（90 - 140GHz）。
